Natives by the Month

Coast Banksia - Banksia integrifolia
This month I sit overlooking the ocean between two coast Banksias a whale in between, and know that the whales and this species ‘Coast Banksia’ have had a long association of thousands of years,
watching each other as the whales pass, perhaps. The timely flowering offered indigenous people a calendar-like moment to remind them that the whale season was close.
A known cultural use of Banksia involves fire-making, as the fine fibre in the spent flower is perfect for initiating natural firestick practices.
This dear old friend, that grows to 16m high, is found throughout the north coast, and inland in NSW, Victoria and southern Queensland.
Locally, I have seen it at The Channon / Keerrong / Wongavale on sandy country, and it is also endemic at Nimbin Rocks.
Tea Tree - Meleauca alternifolia
Revered by the Bundjalung nation of the northern rivers, Tea Tree was a very important cultural plant.
Tea Tree was used to treat wounds with poultices, and crushed leaves for inhaling in the treatment of colds. The anti-fungal properties of Melaleuca alternifolia was very important, particularly when living in swampy places, where Tea Tree is endemic.
Melaleuca alternifolia is a small tree that grows to several metres where it enjoys seasonal wet feet. It also grows happily in drier areas, and thrives in full sun or in the understory.
Whilst big areas are now under broad acre production on the Northern Rivers, it wasn’t so long ago that wild harvesting of Tea Tree on private land to distill your own oil was a simple, viable, clean and ethical product.
In Nimbin, I have friends in a community who have an ageing paddock of Tea Tree that has grown well and could easily be chain sawed and the regrowth harvested and distilled. Those wanting to grow their own will find this an easy tree to grow.
Brush Cherry - Syzygium australe
Syzygium australe is a small tree found in all types of warm rainforest. Commonly known as Brush Cherry, it is very common on the North Coast, particularly in the Nimbin area, and it is edible.
It is often found in damp gullies and by creeks. Purple/maroon fruits hang in abundance from winter to spring, and are a favourite bush tucker for the kids.
This very attractive evergreen tree is easy to grow and makes an excellent screen, garden or native planting for most situations.
For those interested, there is a very old tree on Calico Creek (on Blade Road, opposite the tip) that looks to have had many a camp and feast over the last couple of hundred years.
Broad-leaved palm lily - Cordyline petiolaris
Although palm lilies are a common species in our local forests and remnants, Cordyline petiolaris with its bright red fruits hanging in long spikey clusters stands out like Mr Squiggle in a crowd.
Often found in the midst and edges of rainforest and wet sclerophyll forest, the broad-leaved palm lily with its flat green leaf foliage and summery purple/white flowers looks stunning as part of a filtered sun understory.
Broad-leaved palm lilies are an ideal plant when rehabilitating areas of bushland, whether planted or regenerated.
Cordyline petiolaris can grow to several metres in height. Despite having a tendency to look leggy when over ten years old, it can create a stunning landscape effect, particularly when mixed with the narrow leaves of the other red fruited palm lily (Cordyline ru’ora).
To propagate your own plants, sift fruits through a metal colander to remove pulp and sow in a well drained seed raising mix. They will germinate easily in a month or two and should be planted into moist well drained soil.
Cinnamon myrtle / Grey myrtle - Backhousia Myrtifolia
Cinnamon myrtle is a hardy small tree found along the NSW coast and SE Queensland. Very common in the Nimbin area, it dominates the creek line vegetation along Webster’s Creek and is also common along Goolmangar Creek, where its cream/white flowers warm up the summer landscape. Its dense form protects the creek line in times of the all too common raging torrents.
This is a great plant to introduce onto your regeneration projects as it copes with full sun and is reasonably hardy in frosty conditions, though I do recommend protection when young. It is also a good plant on the farm as it is a handsome landscape and screen plant, its dense green leaves introducing the enthusiast into the rainforest environment.
Those interested in bush foods will find interesting its popularity in the 90’s as a recommended spice plant, and hence the name given by Peter Hardwick ”Cinnamon Myrtle”.There were certainly some good selections available some years ago, if you see Peter have a yarn with him about it.
To grow your own, collect ripe seed in autumn and it is also reliable by cuttings, which is recommended. To see some specimens, they are quite common around the Webster’s Creek bridge at Stony Chute and in a landscape environment at the memorial baths in Lismore.
Bangalow Palm - Archontrophoenix cunninghamiana
Bangalow palms, which grow to about 9m, are found mostly in moist situations, often along stream banks and wet alluvial flats, and sometimes on hill slopes.
The leaves of the Archontrophoenix cunninghamiana are large – up to several metres long – glossy and dark. In the spring, purple flowers create a striking appearance as they flower at the top of the trunk.
In early Summer, bright red fruit are borne in panicles below the tuft of leaves and add colour to go with the festive cheer.
Bangalow palms are common in this area, often found close to the source of subtropical rainforest remnants and regrowth. To see these palms near Nimbin, take a look towards Nimbin Rocks when standing a few kilometres out of town on the Nimbin Road. The palm valley below the cliffs is spectacular! Further afield, Protester’s Falls offers a chance to walk amongst these palms.
In the garden, the Bangalow palm is hardy and rewarding as it copes well in most situations. It can tolerate full sun and strong winds, but not frost.
It is easy to propagate with older seed from the forest floor. Only propagate from remnant rainforest groups of palms as domestic plantings could possibly cross breed with Alexander palms, a native of north ueensland, which is now widely planted in the area. Alexander palms are distinguished by the silver scales on the undersides of the leaflets.
Brown Kurrajong - North Coast Christmas Bush
The colours of the festive season abound this month. Following from the red and pink flush of new growth of spring, we have an abundance of flowers at this time of the year.
One of the most noticeable is this shrub or tree, the Brown Kurrajong. Also know as North Coast Christmas Bush, this common tree with its clusters of densely covered white flowers is certainly the backdrop to early summer.
A common tree of drier rainforest margins, this species is good tree for establishing some canopy in your biodiversity plantings.
North Coast Christmas Bush has particular cultural importance, as the bark when stripped and treated makes a valuable twine.
Goori friends down on the coast still enjoy creating this and showing the available wares of our valuable bush heritage.
To grow your own, collect the bristly brown (dry) seed capsules in late summer and blend the lot and sow in your sandy prop mix. The fruits contain a number of tiny hard brown seeds.
Palm Lily, Cordyline - Cordyline stricta
Cordyline stricta is one of my real favourites. Strictly it’s not local to the valleys of Nimbin, but it’s common on and closer to the coast, where it can be found growing alongside and underneath paperbarks in the wetlands that remain in that area.
In Nimbin, I’ve found this hardy multi-trunked Palm Lily to be very rewarding in the garden, as it is able to take full sun, dry and wet conditions and looks pretty nice against a wall, or in a subtropical garden setting and along bushland and garden paths.
Purple flowers in spring are followed by black berries in late summer, which make for easy propagation.
Note that this plant is endemic to coastal regions around Ballina and Byron Bay area. Useful as a backdrop in the garden, filling gaps along a fence line or path, and will enhance a garden with remnant native vegetation as an endangered local plant
