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.

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 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.

Oil Ti-Tree Pkt
Melaleuca alternifolia, is notable for its essential oil which is both anti-fungal, and antibiotic, while safely usable for topical applications. This is produced on a commercial scale, and marketed as Tea Tree Oil. The Ti tree is presumably named (Tea Tree) for the brown colouration of many water courses caused by shed leaves from this species. Melaleuca are closely related to the Bottle Brush and need similar conditions. Frost resistant down to -2C

Honey Myrtle Pkt
Thymifolia, closely related to Callistemon (Bottlebrushes), is one of the most widely cultivated members of the genus forming a small 1 metre shrub. It has beautiful, purple, feathery mauve/violet flowers in clusters on the older stems with a distinctive “claw” configuration. Needs good drainage coupled with regular watering to do well. It prefers a sunny position to flower and is not frost tolerant so best suited for conservatory pot use. An unusual shrub not often seen in cultivation in the UK flowering in the second year from seed.

Waratah 10 seeds җ
This hybrid semi-hardy waratah was the result of a deliberate attempt to hybridise Telopea speciosissima and Telopea mongaensisin 1962. It has excellent quality flowers and is hardy to about -5C given a well drained soil and a sheltered position.Telopia is the floral emblem of New South Wales, and a spectacular but challenging flower to grow as a pot plant in the UK, although easy to germinate from seed. The Waratah is a stout, erect shrub which may grow to 4 metres. The dark green leathery leaves, 13-25 cm in length, are arranged alternately and tend to be coarsely toothed. The flowers are grouped in rounded heads 7 to 10 cm in diameter surrounded by crimson bracts, about 5 to 7 cm long. It flowers from September to November and responds well to pruning which encourages flowering the following year, and overcomes the natural tendency of the shrub to assume a straggly shape. It needs a deep sandy soil but with an assured water content to do well and prefers a low nutrient content.

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.
