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.

Cootamundra Wattle (Qty 15 seeds pr Pkt) 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.

Silver Banksia (10 seeds) җ
Banksia, members of the Proteaceae family, is one of Australia’s most beautiful plant genera, named after Sir Joseph Banks. Marginata accepts part shade to full sun and all types of soil with moisture varying from damp through well drained to dry. The plant is also tolerant of salt and lime, although preferring acid to neutral soil. The evergreen leaves are dark green on top and silver underneath which forms an attractive contrast. Flowering in spring and summer, the candle like upright flowers are yellow and borne on spikes 4 to 10cm long and 3 - 5 cm in diameter. Probably hardy to about -10°C it is a spectacular shrub for anyone with a suitable protected position in the UK.

Hardy Bottle Brush (Pr Pkt) җ җ
'Australian Bottle Brush' I have included here some of the best forms of hardy and semi hardy varieties. Rigidus and Salignus Rubra have slightly smaller flowers than some of the more tender species, but well worth growing for an unusual shrub with masses of brilliant bright red flowers about 3” long in early summer. The seed is small, not difficult to grow, with a flowering plant in the second year if sown early. Salignus Rubra is a more weeping and smaller variety. Captain Cook is a weeping large flowered form of Viminalis but also reasonably hardy for milder areas.

Lacy Tree Fern (Pr Pkt)  җ
Cyathea Cooperii is an attractive garden tree fern suitable for a sheltered site. However it is not so hardy and temperatures of minus 4C are at the limit of its endurance. It is taller and more slender than Dicksonia with soft light green fronds.

Dicksonia antarctica

Hardy Tree Fern (Pr Pkt) җ җ
One of the most beautiful species of plant to come from the southern hemisphere are the tree ferns. Alas our winter climate is a little harsh for them 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.

Erythrina crista-galli

Common Coral Tree (10 seeds) җ
Another plant I have grown for years but it really needs a hot sunny conservatory to do well. Long terminal spikes of typical pea family bright red flowers. Tall plant flowering at 6ft+ but dies back to ground level in cold climates, watch out for the wicked thorns on the stems though! Easy to raise from seed and fairly fast growing.

Kirstenbosch Smoke Primer

Kirstenbosch 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.
