Down Under Plants

Many of our exotic plants and unusual plants come from the antipodes, in particular the eucalyptus, callistemon, banksia and tree ferns are quite unique. This page explores some of these plants that I have grown and come to love over the years, struggled with and fought with in our unsuitable climate, but nevertheless admired.

Acacia baileyana

Cootamundra Wattle 15 seeds җ
Acacia baileyana is the floral emblem of the small rural township of Cootamundra is a well-known Australian species, principally on account of its popularity in cultivation. Baileyana grows to a large bushy shrub or small tree, commonly reaching 5–10 m high, and is typically freely branching from 1–2 m above the ground, plants growing in dense regrowth stands tend to be somewhat spindly whereas in open sites they are more robust. The short bipinnate leaves are usually grey/green in colour, the flower heads are lemon yellow and arranged in elongated showy racemes. Cootamundra Wattle is an adaptable, fairly hardy species that is fast-growing, relatively short-lived, frost resistant to perhaps -5°C prefering cool, higher rainfall areas.

Actinotus helianthi

Flannel Flower aprx  50 seeds

Flannel flower is a herbaceous or shrubby plant native to New South Wales reaching almost a metre in height in good conditions but is usually much smaller if grown in pots. The leaves are deeply lobed, grey and velvety in nature, giving rise to the common name. The small flowers occur in clusters surrounded by velvety, "petal-like" bracts. The overall appearance of each head of flowers is similar to a daisy.

It is relatively easy to cultivate in sandy soils or in raised beds or pots. Plants may not be long lived but, once established, will often "self-sow" so that new plants replace the originals. Good drainage is essential.

Cyathea dealbata

New for 2015!

Silver Tree Fern Pkt 

Cyathea dealbata, also known as the silver tree fern or silver fern is a species of medium-sized tree ferns, endemic and symbolic to New Zealand. It can grow to heights of 10 m or more with a dense crown of long (4m) fronds that have a silver-white colouration on the undersides. This distinctive silver colouration has made them useful for laying along tracks for night walking. Once established, it will tolerate drier conditions but it does best when sheltered from strong winds and frost in a well drained shady damp position. For the UK it needs to be kept pot grown (which will also contain its ultimate size) and brought under glass for winter.

Dicksonia antarctica

Hardy Tree Fern (Pr Pkt) җ җ
Dicksonia antarctica  is one of the most beautiful species of plant to come from the southern hemisphere within the tree ferns. Alas our winter climate is a little harsh for most tree ferns unless a micro climate and suitable winter protection can be established. They are true ferns and hence need shade and high humidity as well as clement winter temperatures. The hardiest is Dicksonia Antartica capable of managing -5°C to -8°C without protection although the fronds will burn and die back at these lows. However if the crown is suitably protected in winter they can survive much lower temperatures and the 5' to 10' fronds in early summer are breathtaking. For those of you living in warm coastal waters or in a protected suburban environment where shade and humidity can be maintained in summer along with mild winter temperatures, these are essential for your tropical garden. They take years to grow and therefore becoming protected in the wild as pressure grows for more garden plants worldwide. You can grow them from spores and although it will take time to grow a tree fern which develops a trunk, the smaller plants are extremely attractive as large ferns.

Fynbos Smoke Primer

Fynbos Smoke Papers (Pkt of 5)

Many seeds can benefit from soaking in smoke impregnated water solution to simulate seed growth after natural bush fires in countries like Australia and South Africa. In particula Anigozanthus, Strelitzia and Protea benefit from this treatment enhancing the likely germination % but research suggests many other recalcitrent species can also benefit like Palms and Musa seed.

Cape Super Smoke Plus is an absorbent paper that is impregnated with fynbos-smoke-saturated water. The paper is then dried and sealed in a polythene packet. When dormant seeds require "smoking", a predetermined volume of water is added to the paper in a suitable container and the seeds are "smoke-primed" by soaking in the smoke-water solution for 24 hours. In order to have the maximum effect in breaking seed dormancy, a range of natural germination stimulators has been added to the smoke solution to overcome other forms of seed dormancy found in many species.

Each standard packet contains five papers, and 50ml water should be added to each paper. Each packet is thus sufficient to make up 250ml solution ( approx. 8½ oz. ) and enough to treat approximately 500 large seeds.

Metrosideros fulgens

New for 2015!

'Scarlet Rata Vine' Pkt

Metrosideros fulgens or Scarlet Rata is a forest vine endemic to New Zealand. The scarlet rata is one of the better-known species of rata vines, because it flowers in the autumn or winter, and is often highly visible growing over road side trees. Its displays of large red flowers are quite spectacular given the right light.

The plant prefers warm moist habitats and in the wild grows up to 10m long or more. It climbs in the same way as ivy, sending out short adventitious roots to adhere to the trunks of host trees, penetrating and clinging to rough surfaces. It will tolerate a light frost but an interesting choice for a cool greenhouse or conservatory where it can be kept to size by pruning where it will take on more of a shrubby habit rather than a vine.
