Habitat Aspect Climate:

Zanthoxylum brachyacanthum prefer light dappled shade to full sun. It grows on dry and moist warm subtropical, cool tropical rainforests or gallery forests on slopes, hills and gullies. The altitude ranges from 18 meters ASL to 750 meters ASL.

The temperatures range from minus 2 degree in July to 40 degrees in January.

The rainfall ranges from lows of 900mm to an average of 2800mm annually.

Soil Requirements:

Zanthoxylum brachyacanthum prefer to grow on better quality, deep loams to medium clays. The soils are derived from decomposed brown, black basalts or metamorphic rocks. The soils pH varies from 5pH to 6pH. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 15m to 20m by 5m to 8m.

Characteristics:

Zanthoxylum brachyacanthum grows as a medium tree with grey to mid grey-brown trunk that is covered in hard, pungent, conical prickles. They are more prominent on juvenile trees and are larger and stouter on mature trunks and branches. The branchlets are densely covered in fine the prickles.

Zanthoxylum brachyacanthum’s alternate, pinnate even leaves measure 100mm to 400mm in length. The 6 to 18 opposite leaflets are lanceolate, oblong-elliptical or rarely oblong measure 25mm to 100mm in length by 10mm to 50mm in width. The petioles measure 50mm to 150mm in length while the petiolules measure 2mm to 8mm in length. The bases are symmetrical to slightly asymmetrical, broadly cuneate to cuneate-rounded while the apexes are acuminate to bluntly acuminate. The discolourous laminas are grass-green to deep sea green and glabrous on the upper lamina while the lower lamina is slightly paler. The margins are entire or widely and shallowly crenate with an oil gland at each indentation. They curve slightly upwards. The midvein is prominent on the lower lamina and distinctly visible from above being paler in colour.

The inflorescences of Zanthoxylum brachyacanthum are born on dioeciously terminal panicles which measure 50mm to 80mm in length. The peduncles measure 3mm to 4mm in length. The 4 pale yellow-green sepals measure 1mm to 2mm in length. The 4 petals are pale yellow-green or pale pinkish-red externally and are white to pale yellow internally. The petals measure 3.5mm to 5mm in length.

The 4 stamens on the male flowers measure 5mm to 6mm in length. The 4 pale yellow staminodes on the female flowers measure 0.5mm to 0.8mm in length.

The swollen, lime green, urceolate style measures 1.5mm to 1.8mm in length. The stigma is red to burgundy red in colour. Zanthoxylum brachyacanthum flowers appear from late September to late November.

Zanthoxylum brachyacanthum’s fruit is an obovoid to cocci capsule. The capsules measure 7mm to 10mm in length by 5mm to 8mm in diameter. The capsules are tuberculate and turn red on ripening. The single, ovoid, glossy, black seed measures 6mm in diameter.

Wildlife:

Zanthoxylum brachyacanthum is the host plant for the citrus orchard butterfly (Papilio Aegeus).

It is not known to the author whether the plants leaves, pericarps, seeds or sap are edible or not. It is closely related to the Chinese Sichuan Pepper and being a member of the Rubiaceae family indicates that it would not be toxic and in fact may have long term health benefits.

According to Cabi the plants leaves contain the following essential oils: a-pinene (46mm) Bet-caryophyllene eux(14mm) and bicyclogermacrene (12.5mm) These oils, essential oils would indicate that the plants could offer a strong native flavouring in cooking and preserving spicy foods. I have not ventured into its uses but can envisage kangaroo laced with the leaves seed husks or flowers for an exquisite entrée or main course. http://www.cabi.org

The following data is in part from Yeung Him-Che’s handbook of Chinese Herbs and Formulas. This is excellent reading for informed uses of Herbs and their uses. It refers to the Sichuan Pepper, Zanthoxylum simulans.

It is astringent, diaphoretic and emmenagogue. The pericarp is anaesthetic, diuretic, parasiticide and vasodilator. It is used in the treatment of gastralgia and dyspepsia due to cold with vomiting, diarrhoea, abdominal pain, ascariasis and dermal diseases. It has a local anaesthetic action and has been used locally on toothaches.

It is a parasiticide at least against the pork tapeworm which is probably the real reason why Chinese initially used a lot of it when cooking traditional Pork dishes.

The pericarp contains geraniol. In small doses this has a mild diuretic action, though large doses will inhibit the excretion of urine. There is a persistent increase in peristalsis at low concentration, but inhibition at high concentration.

The leaves are carminative, stimulant and sudorific. The fruit is carminative, diuretic, stimulant, stomachic and tonic. The seed has antiphlogistic and diuretic. The resin contained in the bark, and especially in that of the roots, is powerfully stimulant and tonic for the blood system.

Cultivation:

Zanthoxylum brachyacanthum is an unusual ornamental small tree that should be grown in association with other rainforest specie or as a small feature tree in small gardens. It is ideal at the edge of a rain forest gardens or deep in the center of the rainforest. It also make great park trees offering quick growth, and good shade. In cultivation it will grow from 8 meters to 10 meters in height by 6 meters to 8 meters in diameter when grown in the open or taller and narrower if grown closer together as a rainforest tree.

Because the trees develop large prickles it should be planted back from paths and when used as feature trees are best where it will not be grabbed easily.

It grows exceptionally well on light clays with copious amounts of leaf litter to keep the soil cool and moist at all times. If these requirements are met it can cope with temperatures as low as minus 5 degrees and up to 36 degrees. It is moderately drought resistant.

Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period.

It often reaches its full potential in just 4 to 5 years and flower from the fifth year from seed.

This tree could be used as bonsai plant as I have seen some trees in the forest that have grown in some very difficult conditions and have taken on some weird shapes.

Propagation:

Seeds: Seeds of Zanthoxylum brachyacanthum can be removed easily from the follicles.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house. Germination is rather erratic.

When the seedlings are 20 to 25 mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Fertilize using Seaweed, fish emulsion or organic chicken pellets soaked in water and apply the liquid on an alternate basis. Fertilize every 2 months until the plants are well established then on an annual basis in September or March to maintain better health, vitality and flowering.

The altitude ranges from 5 meters ASL to 1000 meters ASL in the north and from 5 meters ASL to 20 meters ASL in the south.

The temperatures range from 2 degrees in July to 36 degrees in January.

The rainfall ranges from lows of 770mm to 2800mm average per annum.

Soil Requirements:

Zeuxine Zeuxine oblonga usually prefers to grow on better quality, deep loams to medium clays. The soils are derived from decomposed brown, black basalts or metamorphic rocks. The soils pH varies from 5pH to 6pH. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 0.1m to 0.35m by 0.1m.

Characteristics:

Zeuxine oblonga grows as a small terrestrial herb with long white rhizome. The rhizome measures 20mm to 60mm in length by 2mm to 4mm in diameter.

The 3 to 7 alternate leaves of Zeuxine oblonga are often on the apical section of the scape. The ovate to broad elliptical, fleshy leaves measure 30mm to 80mm in length by 12mm to 30mm in width. The sessile leaves bases are sheathing while the apexes are acute. The sheaths measure 15mm to 30mm in length and are sparsely to moderately covered in long white pilose hairs. The discolourous laminas are mid grass-green to deep olive-green, semi glossy and moderately covered in very short, soft, white canescent hairs on the upper lamina while the lower laminas are paler and densely covered in very short, soft, white canescent hairs. The laminas decurve downwards from the midvein to the margins and decurve from the base to the apex. The margins are entire and undulate.

The inflorescences of Zeuxine oblonga are scapes born from the rhizome. The deep purple scapes are fleshy, brittle and moderately to densely covered in long, soft, white pilose and hirsute hairs. The scapes measure 100mm to 300mm in height while the spikes measures 20mm to 70mm in length. The petioles measure 5.5mm to 8mm in length including the 4mm to 6mm long by 1.5mm to 2mm wide ovary. The flattened tubular flowers never fully open. The 3 to 30 crowded, individual flowers are resupinate, porrect and measure 4mm to 6mm in length by 3 mm to 4mm in width. The papery floral bract is off white and clasping with a long acute apex.

The dull olive-green and white dorsal sepal has pinkish margins and is covered in long, soft, white pilose and hirsute hairs externally and is glabrous internally. The porrect hooded dorsal sepal measures 4mm to 4.5mm in length by 2mm to 2.5mm in width.

The free dull olive-green and white dorsal sepal has pinkish margins and is covered in long, soft, white pilose and hirsute hairs externally and is glabrous internally. The divergent lateral sepals measure 3mm to 3.5mm in length by 1.5mm to 1.8mm in width.

The oblong, white lateral petals are enclosed by the dorsal sepal and measure 3.5mm to 4mm in length by 1.5mm to 1.8mm in width.

The labellum measures 4mm to 5.5mm in length by 3.5mm to 4mm in width. The labellum is white externally and has a deep yellow throat internally while the apex divides into 2 broad oblong spreading wing like lobes. The lobes margins are entire entire and undulate. The base has 2 white linear to reniform calli while the column is erect and stout. The column measures 1mm to 1.2mm in height while the column foot is absent.

Zeuxine oblonga’s fruits are erect, angulated, fusiform capsules. The mid olive-green to deep olive-green capsules have 4 linear prominent longitudinal ridges. The capsules are moderately covered in soft, long white hirsute hairs and fine tuberculate lumps. The capsules dehisce longitudinally with the 4 sides and 4 ridges separating in the middle but remain joined at the base and apex.

Wildlife:

Zeuxine oblonga’s wildlife is unknown to the author.

Cultivation:

Zeuxine oblonga is an interesting orchid for cultivation yet it appears that it has not found its way into horticulture to date. Its requirements are simple dark, humid positions that are wet during the growing season with a sharp coarse sandy fertile mix.

If you are fortunate enough to have it growing naturally it is best to leave it where it is and place a small fence or border of rocks or logs around it to protect it.

Propagation:

Seeds: All orchids that are declared rare, vulnerable or endangered are protected by Federal and State Laws and must not be removed from the wild unless you are a land developer, mining company or main Roads department etc. This includes bulbs, roots, leaves and flowers. No part of any plant can be removed from Federal, State or Local Government land without the prior permission of the authority and this includes the spore.

1. Obtain relevant materials

The first step in growing orchid from seed will be sourcing and having at the ready all materials that will be required in the propagation process.

This includes all of the following:

Unripe orchid seed capsule. If there are 2 capsules secure the second capsule immediately after the first capsule splits or if only one capsule as soon as it changes colour.

Orchid gelling medium with agar which can be purchased from an orchid society or a specialist nursery.

Distilled water

Cooking pot

Spoon

Oven-safe glass or polypropylene containers with lids

Sealable bags

Clean, sterilized cutting board

Rubber gloves

Paper towels

Tweezers or forceps

70 percent ethanol

Bleach

Scalpel or sharp knife

Planting pot

Orchid compost

Length of wire metal

Plastic spray bottle.

deep petri dishes or sterile jars.

2. Prepare agar medium

The agar medium is a special orchid gelling mixture that distilled water will be added to distilled water.

To prepare the medium, mix equal parts of orchid gelling medium with distilled water in a cooking pot.

Place the pot on a stove and bring the mixture to boil for while stirring continuously for two minutes.

Pour the mixture into the petri dishes glass or propylene containers while ensuring not to fill the containers above 20 percent of their volume.

Loosely replace the lids to the containers. Sterilize the containers by heating them up in a microwave oven for between 2 to 3 minutes.

Spray 70 percent ethanol into a sealable bag to create a sterile environment. Transfer the heated containers into the sealable bag.

Allow the containers to cool a bit before tightening their lids and then sealing the bag. Leave the containers to stand for a few days until the mixture solidifies.

3. Prepare seed capsule and work surface

Place an open pot of water on a stove and bring to boil. Place the cutting board in the oven and sterilize.

Put on rubber gloves and sterilize the forceps, and scalpel with 70 percent ethanol.

Insert the seed capsule into a bowel filled with bleach for about fifteen minutes.

Sterilize seed capsule again with 70 percent ethanol and place on grill.

Using the sterilized scalpel, cut open the seed capsule to reveal the seeds. Using a scalpel or sharp knife, scrape out the seeds from the capsule unto an ethanol soaked paper towel.

4. Flasking of the seed

Take out the petri dishes or glass jars containers holding the agar medium. Over the steam, open up the containers and transfer seeds from the ethanol soaked paper towel into the individual containers using the sterilized forceps.

The amount of seeds will determine the number of containers required.  Replace the lid of the containers and place them on  a window sill that receives indirect sunlight.

5. Wait and exercise patience

All that can be done at this point is to wait until the seeds germinate. The amount of time that this might take varies and is dependent on the particular species.

Generally, the time can range from a few months to a few years. During this period of waiting, ensure the containers are free from contamination to ensure that germination is not disrupted.

6. Emergence of protocorms

Protocorms are tuber-shaped bodies with rhizoids that are produced by the young seedlings of various orchids. Protocorms represent the embryonic form of the orchid plant.

Their emergence after the period of waiting at an affirmation that everything in the propagation process is on track.

7. Transflask orchid seedlings is done after they have developed roots

Upon the emergence of the protocorms, consistently observe the growth of the seedlings. At the point when the seedlings appear to overcrowd the flask, transflasking should be carried out, typically within 30 and 60 days.

* This is done by removing individual seedlings using sterilized tweezers from the original containers and placing them in new containers also filled, in a proportion similar to the original, with agar medium. 6 to 8 in a standard petri dish or 1or 2 to a test tube

8. Transplant seedlings into planting pots

On the presumption that there are no disruptions to the plant growth, the seedlings will eventually outgrow the containers.

At this point, they are to be transplanted into planting pots. A good rule of thumb to determine when they are ready to be transplanted is when the seedlings have developed roots that have grown up to the length of one-quarter of an inch.

To transplant, prepare a planting pot or other container for receiving the seedling by majorly filling it up with coarse fir bark and possibly some slightly moist orchid compost mixture containing perlite, fine charcoal, redwood bark shavings, etc.

To extract the seedlings, submerge the containers in warm water to help loosen the agar gel.

Once the agar medium is softened, twist a piece of metal to form a loop and in turn, use it to carefully pull out the seedlings from the container. It is best done if the agar and seedling can be removed together.

The seedlings can be further rinsed in lukewarm water to remove any excess agar mixture still stuck to them.

Following this, the seedlings can now be planted into the prepared pot with at least 50mm of space between each individual seedling.

9. Positioning the orchid

The seedling once fully transplanted should be placed in a location that is warm with good indirect sun light.

Slowly position the pots into an area that closely assimilates the conditions it will be growing under.

The choice as to whether the plant should be exposed to full sun or in direct sunlight will be dependent on the particular orchid specie.

10. Subsequent care of the plant

After the first week, the seedling can be misted several times a day and watered just once a week.

A guide in watering the plant will be using the dryness of the fir back that is, water the plant until the fir back is completely moistened and wait till it has completely dried out before watering again.

Do not fertilize until the seedlings have fully established themselves.

Zieria arborescens prefers light dappled shade to full sun. It grows in moist, warm, sclerophyll forests, dry sclerophyll forests (Zieria arborescens subsp. deccurens) adjacent to moist, warm, and subtropical, moist, gallery forests on flats slopes, hills or gullies. The altitude ranges from 30 meters ASL to 900 meters ASL.

The temperatures range from minus 4 degree in July to 34 degrees in January.

The rainfall ranges from lows of 500mm to an average of 2100mm annually.

Soil Requirements:

Zieria arborescens prefers better quality, deep light clays to medium clays. The soils are derived from decomposed brown basalts, black basalts, shale, metamorphic rocks, granites or sandstones. The soils pH ranges from 5pH through to 6.5pH are preferred. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 2m to 10m by 1.5m to 7m.

Characteristics:

Zieria arborescens’s grows as a medium shrub to small tree with angulated stems. The tan to reddish-brown stems are glabrous, or sparsely to densely covered in white pulverulent and or hirsute and glandular hairs. They are more prominent on juvenile stems and new growth.

The opposite, trifoliate, narrow elliptical, oblong to lanceolate leaflets of Zieria arborescens measure 45mm to 100mm in length by 5mm to 15mm in width. The center leaflet is variable compared to the 2 lateral leaflets. The deep green to sea-green petioles measure 12mm to 30mm in length while the leaflets are sessile. The lateral leaflets are sessile while the center leaflet petiolule measures 2.5mm to 4mm in length. The bases taper to the petiole or petiolule while the apexes are acute. The discolourous laminas are deep green to sea-green and glabrous on the upper laminas while the lower laminas are paler and covered in off white hirsute and stellate hairs. The laminas recurve slightly upwards from the midvein then decurve downwards near the margins and decurve gently downwards on the apical half. The margins are entire. The midvein and pinnate lateral veins are prominent on the lower lamina and depressed on the upper lamina.

The inflorescences of Zieria arborescens are loose panicles born from the leaf axils. The panicles measure 30mm to 80mm in length. There are 10 to 30 flowers on the panicle. The 4 deep green to sea-green calyx lobes are triangular and are covered in off white tomentose or hirsute hairs externally and are glabrous internally. The lobes measure 1.3mm to 2.2mm in length. The 4 oblong white to pale pink petals are sparsely covered in short, soft, white canescent hairs externally and are glabrous internally. The petals apexes are broad obtuse with an apiculate tip and measure 3.5mm to 6.5mm in length by 2.5mm to 4mm in width.

The 4 alternate, white, filaments measure 1mm to 1.6mm in length. The short, flattened, oblong, abaxially, dorsifixed anthers have a truncate base and obtuse apex. The anthers measure 1mm to 1.5mm in length by 0.75mm to 1mm in width.

The short pastel green, urceolate style measures 0.3mm to 0.5mm in length. The flowers appear from September to late December.

Zieria arborescens’s fruit is an obovoidal, glabrous 4 chambered cocci. The cocci are covered in minute oil glands and measure 3mm to 4.5mm in length by 1.5mm to 2.5mm in width. The green tuberculate cocci turn tan when ripe. The style is persistent at the apex of the ripe cocci.

Confusing Subspecie Varieties:

Zieria Zieria arborescens subsp. arborescens grows as a robust shrub or small tree to 10 meters in height. The younger stems are slightly ridged and are scurfy to sparsely to moderately covered in white pulverulent and short stellate hairs or rarely glabrous. The older branches are glabrous or at times are covered in small papillate lumps.

Zieria arborescens subsp. deccurens’s grows as a robust shrub to 3 meters in height. The stems are distinctly ridged particularly on the older sections and are not papillate. The new growth is moderately covered in white hirsute hairs with scattered stellate hairs which are denser between the ridges. The older branches are glabrous or rarely sparsely covered in hirsute in between the ridges.

Zieria arborescens subsp. glabrifolia’s grows as a robust shrub to 4 meters in height. The younger stems are glabrous.

Wildlife:

Zieria arborescens is the host plant for the citrus orchard butterfly Papilio aegeus.

The leaves have a very strong scent of aniseed crossed with citrus when crushed and can be used as an herb to flavor bland foods like potatoes, rice or even used in baking.

Cultivation:

Zieria arborescens is an unusual ornamental shrub that can be grown in association with other rainforest under story specie or as a small feature tree in small gardens. It is ideal at the edge of a rain forest garden or deep in the center of the rainforest. In cultivation it grows from 2.5 meter to 8 meters in height by 2 meters to 6 meters in diameter depending on which sub specie is grown in the open. It can be regularly tipped pruned in increase bushiness and overall vigor of the plant

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 5 degrees and up to 36 degrees. It is moderately drought resistant.

It often reaches its full potential in just 2 to 3 years and flower from the second year from seed.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a faint citrus aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin. It has also been reported to be a good insect repellant against mosquitoes. I have never had plants available when mosquitoes are present so cannot vouch for this but the aroma certainly would indicate it as a suitable source.

The plants have appeal when planted next to paths so you can brush your hands over the foliage to enjoy the released aroma.

Propagation:

Seeds: The seeds of Zieria arborescens can be removed easily from the ripe capsules. Place the seeds in the vegetable crisper of the refrigerator in a dry calico bag over winter and sow in the spring once the last frosts have subsided. The seeds are erratic and may take several months for all the seeds to germinate.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay as some set back will occur until the new roots emerge.

Cuttings: Fortunately Zieria arborescens cuttings strike relatively easy. Use 100mm to 150mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

1 Prepare the cutting mix by adding two thirds sharp clean river sand, one third peat or one third perlite. These ingredients must be sterilized,

2 Select good material from non-diseased plants, 

3 Select semi green stems for cuttings,

4 Place the cutting on a flat, hard surface, and make a clean cut down one side of the cutting at the base for 10mm with a sharp sterile knife or razor blade. – This scarification of the node will increase the chances of roots emerging from this spot. Now remove all but one or two the leaves, leaving the apex leaves intact. If the leaves are very large in proportion to the stem, cut off the apical halves.

5 Fill a saucer with water, and place a little medium strength rooting hormone into another container like a milk bottle top. Dip the node end of the cutting into the water and then into the rooting hormone. Tap off any excess hormone,

6 Use a small dipple stick or old pencil to poke a hole into the soilless potting mix. Ensure the hole is slightly larger than the stem diameter and be careful not to wipe the rooting hormone off the cuttings base. Place 2 to 4 cuttings in each of the 50mm native tubes,

7 I like to place the tubes in bucket with holes drilled in the bottom to allow excess water to drain out. A plastic bag that fits over the bucket is ideal to help maintain temperature and moisture. Place in a semi shaded, warm position like under 50mm shade cloth.

8 When the cuttings have struck, open the bag to allow air circulation for a few days to a week,

9 Once hardened off remove the cuttings from the bag and allow to further hardening for a few more days to a week,

10 Transplant into a good potting mix to grow on.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September or March to maintain health, vitality and better flowering.

Zieria baeuerlenii prefers light dappled shade to full sun. It grows in Grows in dry sclerophyll forest and closed woodlands. The altitude ranges from 20 meters ASL to 120 meters ASL.

The temperatures range from minus 3 degrees in July to 40 degrees in January.

The rainfall ranges from lows of 600mm to an average of 900mm annually.

Soil Requirements:

Zieria baeuerlenii prefers to grow on better quality, skeletal coarse sands or fine sands and amongst boulders. The soils are derived from decomposed sandstones. The soils pH ranges from 5pH through to 6pH are preferred where the water can drain freely. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 0.5m to 0.8m by 0.5m to 0.8m.

Characteristics:

Zieria baeuerlenii’s grows as procumbent open shrub. The larger stems are mid grey and glabrous. The mid fawnish-green to deep fawnish-green stems are moderately covered in stellate hair short stellate hairs mixed with much longer tomentose hairs.

The alternate, trifoliate, leaflets of Zieria baeurlenii measure 6mm to 11.5mm in length by 4.5mm to 9mm in width. The center leaflet is obcordate, while the 2 lateral leaflets are oblong. The pale pinkish, terete petioles measure 1.5mm to 2.3mm in length. The central leaflet’s base tapers to the petiole, while the apex is emarginate to retuse. The lateral leaflets bases are truncate, while the apexes are obtuse with or without a mucronate tip.

The concolourous, velvety laminas are pale blueish-green, are moderately covered in stellate hair short stellate hairs mixed with much longer white tomentose hairs. The laminas are recurved to revolute with entire margins and decurve downwards from the base to the apex. The margins are entire. The midvein is strongly prominent on the lower lamina, is moderately covered in off white hirsute hairs and is clearly visible from the upper lamina. The pinnate lateral veins are slightly prominent on the lower lamina. The mid vein is prominent on the lower lamina and is clearly visible on the upper lamina.

The inflorescences of Zieria baeuerlenii are small panicles born from the leaf axil. There are 5 to 11 usually 7 individual flowers on the panicle. The panicles measure 10mm to 40mm in length.

The 4 deep green to sea-green calyx lobes are broad triangular and are covered in off white hirsute hairs with a few off white stellate externally and are glabrous internally. The lobes measure 1.5mm to 2.5mm in length. The 4 oblong, valate, white to pale pink petals are sparsely covered in short, soft, white stellate-puberulent hairs externally and are glabrous internally. The petals apexes are broad acute, obtuse or obtuse with an apiculate tip and measure 4.5mm to 6mm in length by 3mm to 4mm in width.

The 4 triangular calyx lobes measure 2mm to 2.5mm in length and are velvety. The imbricate, white to pale pink petals measure 3mm to 3.5mm in length. The 4 petals are sparsely covered in stellate hair short stellate hairs mixed with much longer tomentose hairs externally and are glabrous internally.

The 4 alternate, stout, white, filaments measure 1.2mm to 1.6mm in length. The oblong to triangular, dorsifixed anthers measure 0.4mm to 0.5mm in length.

The short, stout, pastel purple style is glabrous and measures 1.2mm to 1.5mm in length. The flowers appear from September to October.

Zieria baeuerlenii’s fruit is unknown and is presumably thought that the species has lost its capacity to reproduce sexually. The plants resprout following fire from an underground root stock.

Wildlife:

Zieria baeuerlenii associated wildlife is unknown

Cultivation:

Zieria baeuerlenii is a beautiful, densely, compact, ornamental shrub that should be grown in association with other rainforest under story specie or as larger plant in heath gardens within small gardens. It is ideal at the edge of a rain forest gardens or deep in the center of the rainforest. In cultivation it grows from 1 meter to 1.5 meters in height by 0.8 meters to 1.2 meters in diameter when grown in the open. It can be regularly tipped pruned in increase bushiness and overall vigour of the plant but really is not necessary unless a smaller shrub is required or a dense low leafy hedge is being sought.

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if they are given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 5 degrees and up to 36 degrees. It is moderately drought resistant.

It often reaches its full potential in just 2 to 3 years and flower from the second year from seed.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a faint citrus aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin. Here it is reported to be a good repellent against mosquitoes. I have never had plants available when mosquitoes are present so cannot vouch for this but the aroma certainly would indicate it as a suitable source.

The plants have appeal when planted next to paths so you can brush your hands over the foliage to enjoy the released aroma.

Propagation:

Cuttings: Zieria baeuerlenii is declared vulnerable and is protected by Federal and State Laws and must not be removed from the wild unless you are a land developer, forestry, mining company or main Roads department etc. This includes bulbs, roots, leaves and flowers. No part of any plant can be removed from Federal, State or Local Government land or private land.

Fortunately Zieria baeuerlenii cuttings should strike relatively easy so if you are fortunate enough to obtain material legally then give it a go. Use 100mm to 200mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

Propagation:

Seeds: The seeds of Zieria compacta can be removed easily from the ripe capsules. Place the seeds in the vegetable crisper of the refrigerator in a dry calico bag over winter and sow in the spring once the last frosts have subsided. The seeds are erratic and may take several months for all the seeds to germinate.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Cuttings: Fortunately Zieria compacta cuttings strike easy. Use 100mm to 200mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

Family: Rutaceae

Genus: Is named in honour of John Zier; 17??-1796, who was a Polish botanist.

Specie: From Elaphrós/Elakhús, which is Ancient Greek or Levis, which is Latin for swift, light weight, slick or smooth. It refers to leaves or other organs, which are smoother and glossier than other species in the genus.

Sub species:

Common Name: Smooth Zieria or Smooth Leaved Zieria or Twiggy Midge Bush.

Distribution:

Zieria laevigata is found south from Stradbroke Island in south eastern coastal Queensland to Clyde Mountains near Shoalhaven Bay in southern coastal New South Wales. It is mainly found along the coast or on the Great Dividing Range and in the Blue Mountains.

https://avh.ala.org.au/occurrences/search?taxa=Zieria+laevigata#tab_mapView

Habitat Aspect Climate:

Zieria laevigata prefer light dappled shade to full sun. It grows in dry sclerophyll forest heaths or dry coastal woodland wallum heaths. The altitude ranges from 5 meters ASL to 55 meters ASL or 500 meters ASL to 850 meters ASL.

The temperatures range from minus 3 degrees in July to 40 degrees in January.

The rainfall ranges from lows of 500mm to an average of 2100mm annually.

Soil Requirements:

Zieria laevigata prefer to grow on skeletal to deep coarse sands, fine sands or light fatty clays. The soils are usually derived from decomposed sandstones, granites or accumulated peaty beach sands. The soils pH ranges from 4.5pH through to 6.5pH are preferred where the water can drain freely. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 1m to 1.5m by 1m to 1.5m.

Characteristics:

Zieria laevigata grows as an erect bushy shrub with erect stems. The mid brown stems are usually glabrous or at times sparsely covered in white hirsute hairs around the nodes. The new growth and young stems are olive-green and glabrous or at times sparsely covered in white hirsute hairs around the nodes.

The opposite, trifoliate, elliptic to obovate leaflets of Zieria laevigatameasure 15mm to 40mm in length by 1mm to 3mm in width. The center leaflet is more variable compared to the 2 lateral leaflets. The deep green to sea-green petioles measure 2mm to 5mm in length while the leaflets are sessile. The middle and lateral leaflets are sessile. The bases taper to the petiole while the apexes are acute. The discolourous laminas are deep green to sea-green and glabrous on the upper laminas while the lower laminas are greenish white and moderately to densely covered in off white canescent hairs with a few hirsute-stellate hairs. The laminas are retrorse to revolute from the mid vein to the margins and recurve gently upwards from the base and at the apex. The margins are entire. The obtuse, deep green, midvein is glabrous or sparsely covered in off white puberulent hairs and is strongly prominent on the lower lamina and is clearly visible from the upper lamina. The reticulate lateral veins are not prominent and are difficult to see.

The inflorescences of Zieria laevigata are small panicles born from the leaf axil. There are 3 to 23 usually 3 to 6 individual flowers on the panicle. The panicles measure 15mm to 40mm in length.

The 4 deep green to sea-green calyx lobes are broad triangular on the cupuliform calyx. The calyx and 4 lobes are sparsely covered in minute oil glands and are glabrous. The calyx measures 1mm to 1.5mm in length while the lobes measure 2.5mm to 3mm in length. The 4 oblong to narrow spathulate, valvate or slightly imbricate, white to mid-pink petals are sparsely covered in short, soft, white tomentose hairs externally and are glabrous internally. The petals apexes are broad obtuse or truncate-obtuse with an apiculate to cuspidate tip and measure 3.5mm to 5.5mm in length by 2.2mm to 4mm in width.

The 4 alternate, cream or pale pink, filaments measure 1.6mm to 2.5mm in length. The short, flattened, oblong, abaxially, dorsifixed anthers have a truncate base and a broad acute apex. The anthers measure 0.4mm to 0.5mm in length by 0.3mm to 0.4mm in width.

The short pastel green, urceolate style measures 0.6mm to 0.8mm in length. The flowers appear from late June to October.

Zieria laevigata’s fruit is an obovoidal, glabrous 4 chamber cocci. The cocci are covered in minute oil glands and measure 3mm to 4.5mm in length by 1.5mm to 2.5mm in width. The green cocci turn tan when ripe. The style is not persistent at the apex of the ripe cocci.

Wildlife:

Zieria laevigata is the host plant for the citrus orchard butterfly Papilio aegeus.

The leaves are aromatic and can be used as a herb to flavor bland foods like potatoes, rice or even used to flavour baked or grilled fish.

Cultivation:

Zieria laevigata is a beautiful, dense, compact, ornamental shrub that should be grown in association with other rainforest under story specie or as larger plant in heath gardens within small gardens. It is ideal at the edge of a rain forest gardens or deep in the center of the rainforest. In cultivation it is grows from 1.5 meter to 1.8 meters in height by 1.5 meters to 1.8 meters in diameter when grown in the open. It can be regularly tipped pruned in increase bushiness and overall vigour of the plant but really is not necessary unless a smaller shrub is required or a dense foliage hedge is being sought.

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if they are given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 2 degrees and up to 36 degrees. It is moderately drought resistant.

It often reaches its full potential in just 2 to 3 years and flower from the second year from seed.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a faint citrus aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin. Here it is reported to be a good repellent against mosquitoes. I have never had plants available when mosquitoes are present so cannot vouch for this but the aroma certainly would indicate it as a suitable source.

The plants have appeal when planted next to paths so you can brush your hands over the foliage to enjoy the released aroma.

Propagation:

Seeds: The seeds of Zieria laevigata can be removed easily from the ripe capsules. Place the seeds in the vegetable crisper of the refrigerator in a dry calico bag over winter and sow in the spring once the last frosts have subsided. The seeds are erratic and may take several months for all the seeds to germinate.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Cuttings: Fortunately Zieria laevigata cuttings strike easy. Use 100mm to 150mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

1 Prepare the cutting mix by adding two thirds sharp clean river sand, one third peat or one third perlite. These ingredients must be sterilized,

2 Select good material from non-diseased plants,  

3 Select semi green stems for cuttings,

4 Place the cutting on a flat, hard surface, and make a clean cut down one side of the cutting at the base for 10mm with a sharp sterile knife or razor blade. – This scarification of the node will increase the chances of roots emerging from this spot. Now remove all but one or two the leaves, leaving the apex leaves intact. If the leaves are very large in proportion to the stem, cut off the apical halves.

5 Fill a saucer with water, and place a little medium strength rooting hormone into another container like a milk bottle top. Dip the node end of the cutting into the water and then into the rooting hormone. Tap off any excess hormone,

6 Use a small dipple stick or old pencil to poke a hole into the soilless potting mix. Ensure the hole is slightly larger than the stem diameter and be careful not to wipe the rooting hormone off the cuttings base. Place 2 to 4 cuttings in each of the 50mm native tubes,

7 I like to place the tubes in bucket with holes drilled in the bottom to allow excess water to drain out. A plastic bag that fits over the bucket is ideal to help maintain temperature and moisture. Place in a semi shaded, warm position like under 50mm shade cloth.

8 When the cuttings have struck, open the bag to allow air circulation for a few days to a week,

9 Once hardened off remove the cuttings from the bag and allow to further hardening for a few more days to a week,

10 Transplant into a good potting mix to grow on.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September or March to maintain health, vitality and better flowering.

Distribution:

Zieria laxiflora is found south from Five Rocks north of Shoalhaven Bay in central coastal Queensland to Wheeler Creek in the Sydney Basin in central coastal New South Wales.

https://avh.ala.org.au/occurrences/search?taxa=Zieria+laxiflora#tab_mapView

Habitat Aspect Climate:

Zieria laxiflora prefers light dappled shade to full sun. It grows in moist coastal heaths, wallums and swampy areas further inland. The altitude ranges from 4 meters ASL to 60 meters ASL with an exception of a population near Torrington at around 760 meters ASL.

The temperatures range from minus 5 degrees in July to 37 degrees in February.

The rainfall ranges from lows of 700mm to an average of 1700mm annually.

Soil Requirements:

Zieria laxiflora prefers to grow on peaty sands or sandy loams. The soils are usually derived from accumulated beach sands or at times decomposed granites. The soils pH ranges from 5pH through to 6.5pH are preferred where the water can drain freely. It tolerates seasonal water logged soils and seasonal high water tables. Non saline soils to moderately saline soils are tolerated as are salt laden winds.

Height & Spread:

Wild Plants: 1m to 1.2m by 1m to 1.5m.

Characteristics:

Zieria laxiflora’s grows as an open to dense shrub with deep green, glabrous stems. The terete stems are not lepidote and are sparsely covered in minute oil glands near the apexes.

The opposite, trifoliate leaflets of Zieria laxiflora are linear to very narrow oblong and measure 15mm to 55mm in length by 1.5mm to 5mm in width. The center leaflet is more variable and longer than the 2 lateral leaflets. The mid green to deep green petioles are sparsely covered in off white pubescent hairs. The petioles measure 5mm to 10mm in length while the lateral leaflets are sessile. The bases taper to the petiole while the apexes are acute to acuminate. The concolourous laminas are deep green to sea-green, glabrous, glossy and covered in oil glands on the upper lamina while the lower lamina lacks the oil glands and is moderately to densely covered in white to fawnish velvety stellate hairs. The laminas are slightly to strongly convex from the mid vein to the margins and are strongly revolute at the margins. The margins are entire. The midvein is strongly prominent on the lower lamina and clearly visible as a groove on the upper lamina and is covered in white or fawnish pubescent hairs.

The inflorescences of Zieria laxiflora are small cymes or panicles born from the leaf axil. There are 3 to 50 usually 9 to 15 individual flowers on the panicle. The panicles measure 10mm to 16mm in length.

The 4 deep green to glaucous, broader than long triangular, calyx lobes are glabrous and measure 1.2mm to 1.7mm in length. The 4 narrow elliptical to oblong, petals are white to pale pink and are sparsely covered in soft, white tomentose hairs. The petals apexes are broad acute with a mucronate to apiculate tip and measure 3.5mm to 5mm in length by 1.5mm to 2mm in width.

The 4 alternate, pale green, filaments measure 1.2mm to 1.6mm in length. The anthers are cream and measure 0.6mm to 1.2mm in length.

The short pastel green style and 4 lobed stigmas measure 0.3mm to 0.5mm in length. The flowers appear from August to October.

Zieria laxiflora’s fruit is an obovoidal, glabrous cocci. The cocci are sparsely covered in minute oil glands and are slightly lepidote. The green cocci turn red when ripe. The style is not persistent on this specie.

Wildlife:

Zieria laxiflora is the host plant for the citrus orchard butterfly Papilio aegeus.

The leaves are aromatic and can be used as a herb to flavor bland foods like potatoes, rice or even used to flavour baked or grilled fish.

Cultivation:

Zieria laxiflora is a beautiful, dense, compact, ornamental domed shrub that can be grown in association with other open forest trees, under story specie in an open woodland garden or as larger dense foliage plant in heath gardens within small gardens. It is ideal at the edge of a rockery garden mixed with native succulents where it really stands out. In cultivation it usually grows from 0.8 meters to 1.2 meters in height by 0.8 meters to 1.2 meters in diameter when grown in the open. It can be regularly tipped pruned to increase bushiness and overall vigour of the plant but really is not necessary unless a smaller shrub is sought.

It grows exceptionally well on sandy soils and loams with copious amounts of leaf litter or pebble mulch to keep the soil cool and moist at all times. Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 3 degrees and up to 38 degrees once established in the garden. It is not drought tolerant.

It often reaches its full potential in just 2 to 3 years and flower from the second year from seed.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a faint citrus aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin. Here it is reported to be a good repellent against mosquitoes. I have never had plants available when mosquitoes are present so cannot vouch for this but the aroma certainly would indicate it as a suitable source.

The plants have appeal when planted next to paths so you can run your hands over the foliage to enjoy the released aroma and would be an excellent addition to a small aromatic garden bed. I can visualise the plants mass planted in small pockets over a rockery and interspersed with small clumped annuals for additional colour or colourful native succulents.

It could also be used as a small divider or hedge row.

Cuttings: Use 70mm to 90mm long half ripened to ripened material when growing from cuttings from the present season’s growth. Take the cuttings in autumn following the last set of hot weather or early in spring following the last frosts. Carefully remove any buds that may have appeared. Remove half the leaves from the bottom section being careful not to tear the bark.  Remove a slither from the bark from the bottom on one side of the cutting. Using a weak rooting hormone, dip the cutting in and place it in a moist sterile seed raising mix which comprises of 3 parts course sand to 1 part brown or black peat. When the cuttings have obviously struck and have developed good roots treat them as for seedlings.

Fertilize using Seaweed, fish emulsion or organic chicken pellets soaked in water and apply the liquid on an alternate basis. Fertilize every 2 months until the plants are well established then on an annual basis in September or March to maintain better health, vitality and flowering.

Sub species:

Common Name: Headland Zieria

Distribution:

Zieria pilosa is found in an area bounded by Pitwater, Liamena Creek, SE of Mendooran and Northern Budawang Range. There are a few isolated locations to the north at Landsdowne State Forest, Sherwood Nature Reserve and Yuraygir National park. In the south it is found in the Ben Boyd National Park in coastal New South Wales. It is mainly found on and east of The Great Dividing Range to the coast.

Habitat Aspect Climate:

Zieria pilosa prefers light dappled shade growing in dry to moist sclerophyll woodlands and forests. The altitude ranges from 40 meters ASL to 740 meters ASL.

The temperatures range from minus 3 degrees in July to 36 degrees in February.

The rainfall ranges from lows of 700mm to an average of 1100mm annually.

Soil Requirements:

Zieria pilosa prefers to grow on better quality, skeletal sands to sandy loams. The soils are derived from decomposed sandstones. The soils pH ranges from 5pH through to 6pH are preferred where the water can drain freely. It can withstand short periods of water logged soils. Non saline soils to slightly saline soils are tolerated as are salt laden winds.

Height & Spread:

Wild Plants: 0.6m to 1m by 0.3m to 0.6m.

Characteristics:

Zieria pilosa’s grows as an open to semi dense upright bush. The terete yellow-green to deep green stems soon turn reddish-brown and are moderately to densely covered in short, soft, caducous pilose hairs. The angulated stems are ridged, glabrous and sparsely covered in minute oil glands near the apexes.

The opposite, trifoliate leaflets of Zieria pilosa measure 10mm to 25mm in length by 3mm to 7mm in width. The leaflets are linear to oblong or lanceolate, with the center leaflet being more variable and longer than the 2 lateral leaflets. The mid green to deep green petioles are moderately to densely covered in short, soft, caducous pilose hairs. The petioles measure 1.5mm to 4mm in length while the lateral leaflets are sessile. The bases taper to the petiole while the apexes are obtuse with or without a distinct mucronate tip. The discolourous upper laminas are mid green to deep green glabrous, dull to semi glossy, while the lower laminas are paler and slightly to moderately covered in short, soft, caducous pilose hairs and dull. The laminas curve upwards from the mid vein then downwards to the margins and decurve on the apical quarter. The midvein is prominent on the lower lamina.

The inflorescences of Zieria pilosa are born in cymose clusters from the leaf axil. There are 1 to 7 individual flowers.

The 4 mid green calyx lobes are joined at the base and are narrow triangular are slightly to moderately covered in short, soft pilose hairs and measure 2mm to 3.mm in length. The 4 oblong, imbricate, petals are white to pale pink externally and white to pastel pink internally. The petals are slightly to moderately covered in short, soft pilose hairs externally and are glabrous internally. The petals apexes are broad obtuse with a blunt mucronate tip. The petals measure 3mm to 4.5mm in length by 2.5mm to 3.5mm in width.

The 4 alternate, white, filaments measure 2mm to 3mm in length. The short, flattened, oblong, abaxially, dorsifixed anthers have a truncate base and obtuse apex. The stamens are adjacent to the petals.

The short pastel green, urceolate style is sparsely covered with short stellate hairs on the basal half and measures 0.3mm to 0.5mm in length. The flowers appear from early September to January. Plants may have the odd flower all year under favourable conditions.

Zieria pilosa’s fruit is an obovoidal, glabrous cschizocarps, whih have 2 cocci with 2 seeds in each chamber. The cocci are glabrous to slightly covered in short, soft pilose hairs and are free of oil glands. The green cocci turn red when ripe. The style is persistent at the apex of the ripe cocci.

Wildlife:

Zieria pilosa is the host plant for the citrus orchard butterfly Papilio aegeus.

The leaves are aromatic and can be used as a herb to flavor bland foods like potatoes, rice or even used to flavour baked or grilled fish.

Cultivation:

Zieria pilosa would make an interesting garden species and deserve a place in gardens. It requires good drainage, preferably on a light sandy soil and a semi-shaded area. It has soft foliage and could be pruned into nice-rounded shrub to increase flowering prolifically.

It often reaches its full potential in in the first year and flowers from the second year from seed.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a strong aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin. Here it is reported to be a good repellent against mosquitoes. I have never had plants available when mosquitoes are present so cannot vouch for this but the aroma certainly would indicate it as a suitable source.

The plants have appeal when planted next to paths so you can run your hands over the foliage to enjoy the released aroma and would be an excellent addition to a small aromatic garden bed. I can visualise the plants mass planted in small pockets over a rockery and interspersed with small clumped annuals for additional colour or colourful native succulents.

Propagation:

Seeds: The seeds of Zieria pilosa like most Zieria sp. are difficult to obtain. Place the seeds in the vegetable crisper of the refrigerator in a dry calico bag over winter and sow in the spring once the last frosts have subsided. The seeds are erratic and may take several months for all the seeds to germinate.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50% shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay as some set back will occur until the new roots emerge.

Cuttings: Fortunately, Zieria pilosa cuttings strike relatively easy. Use 100mm to 150mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

1 Prepare the cutting mix by adding two thirds sharp clean river sand, one third peat or one third perlite. These ingredients must be sterilized,

2 Select good material from non-diseased plants,  

3 Select semi green stems for cuttings,

4 Place the cutting on a flat, hard surface, and make a clean cut down one side of the cutting at the base for 10mm with a sharp sterile knife or razor blade. – This scarification of the node will increase the chances of roots emerging from this spot. Now remove all but one or two the leaves, leaving the apex leaves intact. If the leaves are very large in proportion to the stem, cut off the apical halves.

5 Fill a saucer with water, and place a little medium strength rooting hormone into another container like a milk bottle top. Dip the node end of the cutting into the water and then into the rooting hormone. Tap off any excess hormone,

6 Use a small dipple stick or old pencil to poke a hole into the soilless potting mix. Ensure the hole is slightly larger than the stem diameter and be careful not to wipe the rooting hormone off the cuttings base. Place 2 to 4 cuttings in each of the 50mm native tubes,

7 I like to place the tubes in bucket with holes drilled in the bottom to allow excess water to drain out. A plastic bag that fits over the bucket is ideal to help maintain temperature and moisture. Place in a semi shaded, warm position like under 50% shade cloth.

8 When the cuttings have struck, open the bag to allow air circulation for a few days to a week,

9 Once hardened off remove the cuttings from the bag and allow to further hardening for a few more days to a week,

10 Transplant into a good potting mix to grow on.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September or March to maintain health, vitality and better flowering.

Family: Rutaceae

Genus: Is named in honour of John Zier; 17??-1796, who was a Polish botanist.

Specie: From Prōstrātum, which is Latin for to throw on the ground or lie on the ground. It refers to plants, which grow flat on the ground.

Sub species:

Common Name: Headland Zieria

Distribution:

Zieria prostrata is restricted to a few beach heads south of Grafton to north of Coffs Harbour in northern coastal New South Wales.

https://avh.ala.org.au/occurrences/search?taxa=Zieria+prostrata#tab_mapView

Habitat Aspect Climate:

Zieria prostrata prefers light dappled shade to full sun. It grows in dry coastal headland heaths along the coast. The altitude ranges from 18 meters ASL to 30 meters ASL.

The temperatures range from 3 degrees in July to 36 degrees in February.

The rainfall ranges from lows of 1100mm to an average of 1700mm annually.

Soil Requirements:

Zieria prostrata prefers to grow on better quality, skeletal sandy loams to light fatty clays. The soils are derived from decomposed sandstones. The soils pH ranges from 5pH through to 5.5pH are preferred where the water can drain freely. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated as are salt laden winds.

Height & Spread:

Wild Plants: 0.1m to 0.2m by 0.3m to 0.6m.

Characteristics:

Zieria prostrata’s grows as a dense mat forming small ground cover with brown stems which turn deep grass-green towards the apexes. The angulated stems are ridged, glabrous and sparsely covered in minute oil glands near the apexes.

The opposite, trifoliate leaflets of Zierra prostrata measure 8mm to 16mm in length by 3mm to 6mm in width. The center leaflet is more variable and longer than the 2 lateral leaflets. The middle leaflet is oblong to obovate while the 2 lateral leaflets are oblong. The mid green to grass-green petioles moderately to densely covered in off white tomentose hairs and hirsute-stellate hairs. The petioles measure 3mm to 4.5mm in length while the leaflets are sessile. The bases taper to the petiole while the apexes are obtuse. The concolourous laminas are deep grass-green to sea-green, glabrous, glossy and covered in minute oil glands. The laminas are slightly to strongly convex from the mid vein to the margins. The margins are entire. The midvein is strongly prominent on the lower lamina while the pinnate lateral veins are slightly prominent on the lower lamina.

The inflorescences of Zieria prostrata are small cymes or panicles born from the leaf axil. There are 2 to 32 usually 3 to 7 individual flowers on the panicle. The panicles measure 10mm to 16mm in length.

The 4 mid green calyx lobes are triangular and broader than long. The glabrous lobes measure 0.5mm to 1.0mm in length. The 4 oblong, imbricate, petals are mid to deep pink externally and pastel pink internally. The petals are sparsely covered in short, soft, white stellate-puberulent hairs externally and are glabrous internally. The petals apexes are broad acute-obtuse or obtuse with a mucronate to apiculate tip. The petals measure 2mm to 3mm in length by 1.5mm to 2.3mm in width.

The 4 alternate, white, filaments measure 1mm to 1.6mm in length. The short, flattened, oblong, abaxially, dorsifixed anthers have a truncate base and obtuse apex. The anthers measure 1mm to 1.5mm in length by 0.75mm to 1mm in width.

The short pastel green, urceolate style is sparsely covered with short stellate hairs on the basal half and measures 0.3mm to 0.5mm in length. The flowers appear from August to October.

Zieria prostrata’s fruit is an obovoidal, glabrous cocci. The cocci are covered in minute oil glands. The green cocci turn red when ripe. The style is persistent at the apex of the ripe cocci.

Wildlife:

Zieria prostrata is the host plant for the citrus orchard butterfly Papilio aegeus.

The leaves are aromatic and can be used as a herb to flavor bland foods like potatoes, rice or even used to flavour baked or grilled fish.

Cultivation:

Zieria prostrata is a beautiful, rather densely, compact, ornamental domed ground cover that can be grown in association with other open forest trees, under story specie in an open woodland garden or as a larger dense foliage plant in heath gardens within small gardens. It is ideal at the edge of a rockery garden mixed with native succulents where it really stands out. In cultivation it usually grows from 0.1 meters to 0.2 meters in height by 0.5 meters to 0.6 meters in diameter when grown in the open. It can be regularly tipped pruned to increase bushiness and overall vigour of the plant but really is not necessary unless a smaller shrub is sought.

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter or pebble mulch to keep the soil cool and moist at all times. Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 3 degrees and up to 38 degrees once established in the garden. It is moderately drought resistant.

It often reaches its full potential in just 2 to 3 years and flower from the second year from seed.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a faint citrus aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin. Here it is reported to be a good repellent against mosquitoes. I have never had plants available when mosquitoes are present so cannot vouch for this but the aroma certainly would indicate it as a suitable source.

Characteristics:

Zieria smithii grows as a small shrub with deep sea-green stems that are covered in farinaceous lumps and are faintly glabrescent. They are more prominent on juvenile shrubs and are larger and more tuberculate on older stems. The younger stems are slightly ridged, glabrous or sparsely covered in white stellate or tomentose hairs.

Zieria smithii’s opposite, trifoliate leaves are narrow-elliptical, oblong to lanceolate and measure 20mm to 45mm in length by 4mm to 7mm in width. The center leaflet is the longest. The petioles measure 10mm to 20mm in length while the leaflets are sessile. The bases are symmetrical and cuneate-attenuate while the apexes are acute.

The leaves have a very strong flavor of aniseed crossed with citrus and can be used as a herb to flavor bland foods like potatoes, rice or even used in baking.

Cultivation:

Zieria smithii is an unusual ornamental shrub that should be grown in association with other rainforest under story specie or as a small feature in small clumps in small gardens. It is ideal at the edge of a rain forest gardens or deep in the center of the rainforest. In cultivation it grows from 1 meter to 1.5 meters in height by 0.8 meters to 1.2 meters in diameter when grown in the open. It can be regularly tipped pruned in increase bushiness and overall vigour of the plant

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 5 degrees and up to 36 degrees. It is moderately drought resistant.

It often reaches their full potential in just 2 to 3 years and flowers from the third year from seed in the garden.

This shrub would be ideal around swimming pools or in court yards to break up hard lines. The leaves give off a faint citrus aroma when crushed and contain a natural lanoline which is soothing when rubbed into the hands or skin.

The laminas are flat, recurve gently upwards from the midvein to the margins or gently decurve downwards from the mid vein to the margins and decurve downwards near the margins and decurve gently downwards at the base and at the apex. The margins are entire and slightly undulate. The obtuse midvein is strongly prominent on the lower lamina and is clearly visible from the upper lamina and is sparsely covered in white stellate hairs on the upper surface. The pinnate lateral veins are slightly prominent on the lower lamina and are visible from the upper laminas. The pinnate lateral veins are slightly prominent on the lower lamina.

The inflorescences of Zierra southwellii are small panicles born from the leaf axil. There are 3 to 35 usually 12 to 19 individual flowers on the panicle. The panicles measure 30mm to 70mm in length.

The 4 deep green to sea-green calyx lobes are broad, hyaline, triangular, glabrous or scarious and or sparsely covered in off white hirsute hairs externally and are glabrous internally. The lobes measure 0.8mm to 1.8mm in length. The 4 oblong, imbricate, white petals are sparsely covered in short, soft, white puberulent hairs externally and are glabrous internally. The petals apexes are broad acute and measure 4mm to 5.5mm in length by 2.2mm to 3mm in width.

The 4 alternate, pale green, filaments measure 0.9mm to 1.2mm in length. The short, flattened, oblong, abaxially, dorsifixed anthers have a truncate base and obtuse apex. The anthers measure 0.4mm to 0.5mm in length by 0.4mm to 0.5mm in width.

The short, urceolate style and ovary are pale green while the stigma is pastel green. The pistil measures 0.5mm to 0.8mm in length. The flowers appear from late July to October.

Zierra southwellii’s fruits are obovoidal cocci. The cocci are covered in minute oil glands and are glabrous except for a few white stellate-ciliate hairs. The green cocci turn reddish-tan when ripe. The style is persistent at the apex of the ripe cocci.

Wildlife:

Zierra southwellii wildlife is unknown to the author.

The leaves are aromatic and can be used as a herb to flavor bland foods like potatoes, rice or even used to flavour baked or grilled fish.

Cultivation:

Zierra southwellii is a beautiful, dense, compact, ornamental shrub that should be grown in association with other rainforest under story specie or as a small rainforest tree. It is ideal at the edge of a rain forest gardens or deep in the center of the rainforest. In cultivation it is grows from 3 meter to 4 meters in height by 2 meters to 3 meters in diameter when grown in the open. It can be regularly tipped pruned in encourage it to grow as a small tree or large shrub. Pruning will also increase bushiness and overall vigour of the plant.

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if they are given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 4 degrees and up to 36 degrees. It is moderately drought tolerant once established.

It often reaches its full potential in just 8 to 10 years and flower from the fourth or fifth year from seed.

The plants have appeal when planted next to paths so you can brush your hands over the foliage to enjoy the released aroma.

The trees would probably be acceptable to most small epiphytic ferns and orchids looking at the bark but would be best to test it first or have it checked with other growers first.

Propagation:

Seeds: The seeds of Zierra southwellii can be removed easily from the ripe capsules. Place the seeds in the vegetable crisper of the refrigerator in a dry calico bag over winter and sow in the spring once the last frosts have subsided. The seeds are erratic and may take several months for all the seeds to germinate.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Cuttings: Fortunately Zieria southwellii cuttings strike relatively easy. Use 100mm to 150mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

1 Prepare the cutting mix by adding two thirds sharp clean river sand, one third peat or one third perlite. These ingredients must be sterilized,

2 Select good material from non-diseased plants,  

3 Select semi green stems for cuttings,

4 Place the cutting on a flat, hard surface, and make a clean cut down one side of the cutting at the base for 10mm with a sharp sterile knife or razor blade. – This scarification of the node will increase the chances of roots emerging from this spot. Now remove all but one or two the leaves, leaving the apex leaves intact. If the leaves are very large in proportion to the stem, cut off the apical halves.

5 Fill a saucer with water, and place a little medium strength rooting hormone into another container like a milk bottle top. Dip the node end of the cutting into the water and then into the rooting hormone. Tap off any excess hormone,

6 Use a small dipple stick or old pencil to poke a hole into the soilless potting mix. Ensure the hole is slightly larger than the stem diameter and be careful not to wipe the rooting hormone off the cuttings base. Place 2 to 4 cuttings in each of the 50mm native tubes,

7 I like to place the tubes in bucket with holes drilled in the bottom to allow excess water to drain out. A plastic bag that fits over the bucket is ideal to help maintain temperature and moisture. Place in a semi shaded, warm position like under 50mm shade cloth.

8 When the cuttings have struck, open the bag to allow air circulation for a few days to a week,

9 Once hardened off remove the cuttings from the bag and allow to further hardening for a few more days to a week,

10 Transplant into a good potting mix to grow on.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September or March to maintain health, vitality and better flowering.

Ziziphus oenopolia

Classification:

Unranked: Eidicots

Order: Rosales

Family: Rhamaceae

Tribe: Paliureae

Genus: From Ziziphus, which is Ancient Greek from the Persian word ziza for a plant name found in ancient Persia. It refers to the similarities between the plants.

Specie: From Oenone, which is Ancient Greek for a beautiful mountain nymph and Polia, which is Ancient Greek for pale grey. It may refer to the early days of the love affair between Paris and Oenone where there would have been great lust. A good example is the fact that over 300 fly species have been recorded attending the flowers on Ziziphus oenopolia in vane attempts in courtships and mating.

Sub species:

Common Name: Native Jujube.

Distribution:

Ziziphus oenopolia is found in several disjunct populations east from Melville Island across the Top End of the Northern Territory to Cape Melville National Park in the east and cairns in the south in far north Queensland.

https://avh.ala.org.au/occurrences/search?taxa=Ziziphus+oenopolia#tab_mapView

Habitat Aspect Climate:

Ziziphus oenopolia prefers light dappled shade to full sun. It can be found growing adjacent moist, warm, tropical rainforests, gallery forests, littoral rainforests or more often monsoonal vine forests. The altitude ranges from 5 meters ASL to 300 meters ASL in Australia however in China it is found from 500 meters ASL to over 1100 meters ASL.

The temperatures range from 10 degree in July to 40 degrees in January.

The rainfall ranges from lows of 1200mm to an average of 3200mm annually.

Soil Requirements:

Ziziphus oenopolia prefers growing on better quality, deep sandy loams to gritty to gravelly medium clays. The soils are usually derived from decomposed brown or black basalts or sandstones. The soils pH ranges from 4.5pH through to 7pH. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 2m to 8m by 2m to 6m.

Characteristics:

Ziziphus oenopolia’s pale grey main stem or branches are rough and furrowed longitudinally. The deep olive brown stems bend away from the leaf axils in a zig zag pattern. They are covered in cream or pale yellow lenticels and sparsely covered in rusty-red puberulent hairs. The new growth is deep olive green to deep sea green and covered in fawn pilose hairs.

Ziziphus oenopolia’s chartaceous, alternate leaves are ovate, ovate-oblong or broad lanceolate and measure 20mm to 75mm in length by 10mm to 25mm in width. The soft spine like stipules measure 3mm to 10mm in length with one pointing downwards while the second one points upwards. The petioles measure 3mm to 8mm in length. The bases are rounded to strongly oblique while the apexes are acute. The discolourous laminas are olive-green to deep green, glabrous and sparsely covered in short, white puberulent hairs on the upper laminas while the lower laminas are moderately to densely covered in rusty brown pubescent hairs. The laminas are flat while the margins are serrated with 30 to 40 and decurve downwards. The mid vein and longitudinal lateral veins are strongly prominent on the lower lamina and are distinctly visible from the upper lamina. The fine reticulated venation is very dense.

The inflorescences of Ziziphus oenopolia are short cymes born from the leaf axils. There are 5 to 12 flowers on the cymes. The pedicels measure 5mm to 8mm in length. The 5 translucent, blue green calyx lobes measure 1mm to 1.2mm in length and are covered in white puberulent hairs externally and glabrous internally. The 5 petals are pale green with a broadly acuminate apex. They measure 1.2mm to 1.4mm in length.

The 5 alternate, clavate, creamy stamens measure 1.4mm to 1.6mm in length. 

The short lime green, styles and stigma barely protrudes from a gelatinous disc. Ziziphus oenopolia flowers appear from January to February.

Ziziphus oenopolia’s fruits are globular drupes. The drupes measure 7mm to 8mm in length by 8mm to 9mm in diameter. The glabrous drupes turn pale yellow brown on ripening. The 1 or 2 fawn seeds are spherical, rugose, or pitted and measure 2mm to 2.5mm in length by 2mm to 2.5mm in diameter. The fruits begin to ripen in late March.

Wildlife:

Ziziphus oenopolia is unknown to the author however the fruits make a great conserve with tang. The fruits are sweet when collected from the ground but are noticeably tangy when picked even when fully black and ripe. The fruits are collected in China, salted and eaten raw or used as flavouring in many types of spicy dishes to give a sweet and sour flavour. The fruits apparently vary greatly in flavour so I cannot testify to the flavour of the Australian fruits which may vary to a large extent whether they come from the Northern Territory or Queensland.

Cultivation:

Ziziphus oenopolia is an unusual ornamental creeper that can be grown in association with other rainforest under story specie or as a small feature as a scrambling shrub when planted in the open away from other plants. It is ideal at the edge of a rain forest gardens or along creek dry creek beds or riparian zones. In cultivation it grows from 2 meter to 2.5 meters in height by 6 meters to 8 meters in length when grown in the open on a trellis for its fruit. It can be regularly tipped pruned in increase bushiness and overall vigour of the plant and this is recommended when growing for fruit production

They grow exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if they are given an adequate supply of water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a long period. If these requirements are met they can cope with temperatures as low as minus 5 degrees and up to 36 degrees. They are moderately drought resistant.

It often reaches its full potential in just 6 to 8 years and flowers from the fourth year from seed.

This creeper would be ideal to try in a corner of an orchard.

Ziziphus oenopolia would make an ideal bonsai plant for a creeper and good large specimens seen in China measure 60mm or more at the base.

The fruits have a good potential as a commercial crop on podsolic soils in high rainfall areas.

Propagation:

Seeds: Seeds of Ziziphus oenopolia can be removed easily from the ripe capsules.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Cuttings: Fortunately Ziziphus oenopolia cuttings strike easy. Use 100mm to 160mm long semi hardwood cuttings from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

1 Prepare the cutting mix by adding two thirds sharp clean river sand, one third peat or one third perlite. These ingredients must be sterilized,

Zornia muriculata’s stems, leaves, bracts and petioles are densely covered in white pubescent hairs.

Wildlife:

Zornia dyctiocarpa’s wildlife is unknown to the author.

Cultivation:

Zornia dyctiocarpa is an unusual shrub that has not gained wide acceptance by home gardeners. It is ideal mixed in with other low growing dry heath plants. In cultivation it grows from 0.2 meter to 0.4 meters in height by 0.4 meters to 0.6 meters in diameter when grown in the open. It can be regularly tipped pruned in increase bushiness and overall vigour of the plant but is probably better if planted in small clusters of 3 to 5 individual plants. For mass plantings plant it at 200mm to 300mm apart.

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if is given a little additional water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a longer period. If these requirements are met it can cope with temperatures as low as minus 4 degrees and up to 39 degrees. It is moderately drought resistant.

When you design a heath garden which Zornia dyctiocarpa is well suited to don’t use contours to display the plants as heath lands are almost always flat or have a slight rise. On flat ground the bright green leaves and yellow flowers will stand out among other greyish or bluish leaf heaths. Place it in the fore ground close to the path as it is less likely to be over grown. Make the heath garden path narrow so you have to feel the plants as you walk though the garden bed. This gives an extra dimension which many people forget about when designing heath gardens. Plants must be planted close together and be short so you can see over the tallest ones with the exception of one or two plants at the most. These will be feature plants. The idea is to achieve a feeling of expansive flatness.

Place it near old stumps and roots to make the stumps or roots look larger. Select an area of ground and let your hair down and be imaginative and this is the plant that may just change your life. Remember this plant can be rather open in habit so plant it in small clusters.

Propagation:

Seeds: The seeds of Zornia dyctiocarpacan be removed easily from the ripe capsules. The abrasion method has proven very successful for germinating seeds. This involves rubbing the seeds gently between two sheets of very fine sandpaper to reduce the thickness of the seed coat. Place the seeds into a plastic bottle that has a sheet of medium corundum paper glued to the inside surfaces. Shake the container vigorously for several minutes. Check to see if the coating has been partially removed.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 20mm shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Fertilize using Seaweed, fish emulsion or organic chicken pellets soaked in water and apply the liquid on an alternate basis. Fertilize every 2 months until the plants are well established then on an annual basis in September or March to maintain better health, vitality and flowering.

The lower and upper leaflets vary in shape with the lower leaflets usually broader and shorter while the upper leaflets are lanceolate to broad. The lomentum are glabrous or sparsely covered in white ciliate to antrorse hairs.

Zornia muriculata’s stems, leaves, bracts and petioles are densely covered in white pubescent hairs.

Wildlife:

Zornia floribunda’s wildlife is unknown to the author.

Cultivation:

Zornia floribunda is an unusual shrub that has not gained wide acceptance by home gardeners. It is ideal mixed in with other low growing dry heath plants. In cultivation it grows from 0.2 meter to 0.4 meters in height by 0.4 meters to 0.6 meters in diameter when grown in the open. It can be regularly tipped pruned in increase bushiness and overall vigour of the plant but is probably better if planted in small clusters of 3 to 5 individual plants. For mass plantings plant it at 200mm to 300mm apart.

It grows exceptionally well on light clays and sandy loams with copious amounts of leaf litter to keep the soil cool and moist at all times. Add to the above, if is given a little additional water and a little native fertilizer on a regular basis the plants should respond with good flowering and fruit over a longer period. If these requirements are met it can cope with temperatures as low as minus 4 degrees and up to 39 degrees. It is moderately drought resistant.

When you design a heath garden which Zornia floribunda is well suited to don’t use contours to display the plants as heath lands are almost always flat or have a slight rise. On flat ground the bright green leaves and yellow flowers will stand out among other greyish or bluish leaf heaths. Place it in the fore ground close to the path as it is less likely to be over grown. Make the heath garden path narrow so you have to feel the plants as you walk though the garden bed. This gives an extra dimension which many people forget about when designing heath gardens. Plants must be planted close together and be short so you can see over the tallest ones with the exception of one or two plants at the most. These will be feature plants. The idea is to achieve a feeling of expansive flatness.

Place it near old stumps and roots to make the stumps or roots look larger. Select an area of ground and let your hair down and be imaginative and this is the plant that may just change your life. Remember this plant can be rather open in habit so plant it in small clusters.

Propagation:

Seeds: The seeds of Zornia floribunda can be removed easily from the ripe capsules.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. Do not over water as the seeds will rot off before germination takes place. Place the trays in a cool shaded area with 50mm shade cloth in the bush house.

When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Fertilize using Seaweed, fish emulsion or organic chicken pellets soaked in water and apply the liquid on an alternate basis. Fertilize every 2 months until the plants are well established then on an annual basis in September or March to maintain better health, vitality and flowering.

Zoysia macrantha

Classification:

Unranked: Monocots

Class: Commelinids

Order: Poales

Family: Poaceae

Subfamily: Chloridoideae

Tribe: Cynodonteae

Subtribe: Zoysiinae

Genus: Is named in honour of Slovenian botanist Karl von Zois; 1756-1799, who was an Austrian botanist and plant collector.

Specie: From Makros, which is Ancient Greek for large and ántha/ánthos, which are Ancient Greek for the male reproductive organ of the flower or the flower. It refers anthers, which are much longer than other species in the genus.

Sub specie:

Common Name: Prickly Couch.

Distribution:

Zoysia macrantha is found south from Shoalwater Bay in central coastal Queensland to Proper Bay on southern Eyre Peninsular in Southern South Australia.

It is also found on the Bass Straight Islands and along the north coast and east coast of Tasmania.

https://avh.ala.org.au/occurrences/search?taxa=Zoysia+macrantha#tab_mapView

Habitat Aspect Climate:

Zoysia macrantha prefers dappled light shade to full sun. It grows on stabilized coastal dunes, behind mangroves, along tidal estuaries on the margins of brackish swamps or wallums. The altitude ranges from 5 meters ASL to 100 meters ASL.

The temperatures range from minus 2 degrees in July to 42 degrees in February.

The rainfall ranges from lows of 100mm to 2100mm average per annum.

Soil Requirements:

Zoysia macrantha prefers coarse sand, fine sand, light silts to heavy silts. The soils are usually derived from accumulated beach sands, alluvial estuary deposits or mangrove silts. The soils pH ranges from 6pH to 8pH. It does not tolerate water logged soils however plants may be inundated for short periods during king tides and storms surges. Non saline soils to extremely saline soils are tolerated as are salt laden winds.

Height & Spread:

Wild Plants:0.05m to 0.3m by 0.5m to many square meters.

Characteristics:

Zoysia macrantha grows as a strongly rhizomatous and stoloniferous perennial with elongated or decumbent culms. The lateral branches are simple or sparsely branched 2 or 3 times.

The linear leaves of Zoysia macrantha measure 10mm to 160mm in length by 1mm to 4mm in width. The chartaceous sheath is off white. The ligule is a membranous rim of short white hirtellous hairs while the orifice is also a rim of short white hirtellous hairs. The concolourous laminas are mid blue-green and glabrous. The laminas are flat to involute or at times convolute.

Inflorescences of Zoysia macrantha are narrow, compact zigzag racemes. The single raceme measures 20mm to 50mm in length.


The appressed spikelets comprise a single fertile floret without a rachilla extension. The lanceolate, elliptic, oblong or ovate florets are laterally compressed and measure 2mm to 5mm in length. The pedicels measure 1mm to 2mm in length.

The similar, coriaceous glumes are firmer than fertile lemmas. The glumes are lanceolate, oblong or ovate and measures 2.5mm to 4.5mm in length. The glumes are without keels and have a single nerve with a mucronate or at times e narrow obtuse apex.

The translucent lemmas are fully enclosed within the glumes and have a mucronate apex while the palea are without keels and nerves. The lemmas measure 2.5mm to 3.5mm in length. There are 3 anthers. The flowers appear from late November to early March.

Wildlife:

Zoysia macrantha’s are a favourite amongst the many specie of macropods (Kangaroos and wallabies) that inhabit the coastal districts.

Cultivation:

Zoysia macrantha is a fast growing grass for most pastures in marginal saline areas along creek banks and estuaries especially in poorly drained areas. Zoysia macrantha yield good quantities of mulch but must be let go to flower at least once a year to help rejuvenate the seed bank.

Zoysia macrantha makes a hard wearing lawn in coastal districts on average to heavier soils provided full sun and moisture are maintained.

As a lawn it is tuff and reacts very favourably being trimmed on a regular basis. The optimum height appears to be around 50mm to 70mm in height. In warm moist weather it needs mowing on a weekly basis.

Propagation:

Seeds: The seeds of Zoysia macrantha can be removed easily from the plants. After seeding has commenced it is just a matter of running the tractor or other device through the grass and the seeds and trash will accumulate on any open bag or cloth.

Seed can be spread directly over the pasture as soon as the last frosts have abated and the first rain has started.

It can be grown from cuttings, divots or laid as turf.

Fertilize using Seaweed, fish emulsion or organic chicken pellets soaked in water and apply the liquid on an alternate basis. Fertilize every 2 months until the plants are well established then on an annual basis in September or March to maintain better health, vitality and flowering.
