Acacia decurrens is a perennial tree or shrub native to eastern New South Wales, including Sydney, the Greater Blue Mountains Area, the Hunter Region, and south west to the Australian Capital Territory.
It is cultivated throughout Australia and the world, and has naturalised in most Australian states and in Africa, the Americas, Europe, New Zealand and the Pacific, the Indian Ocean area, and Japan. It grows to a height of 2–10 m and it flowers from July to September.
Grows naturally in woodlands, dry forests and heathlands in New South Wales, where moisture level is high. In areas where it has become naturalised, Sydney green wattle (Acacia decurrens) is generally found on roadsides, along creeklines and in waste areas. It also grows in disturbed sites nearby bushlands and open woodlands
Prefers ordinary soil, enriched soil, mildly acidic to mildly alkaline are suitable but mainly good in dry soil for extended periods to constantly moist. (info source: wikipedia.org)

|Germination||1. Pour boiling water over seed, let stand in water for 24 hours, repeat process on seed that did not imbibe. It is called scarification.|
2. Sow seed 1/4" (~3-5mm) deep, tamp the soil, mulch the seed bed.
The seed germinates in 3 - 4 weeks at 25°c.
As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in a sunny position in the greenhouse for their first winter. Plant them out in late spring or early summer, after the last expected frosts, and consider giving them some protection from the cold for their first winter outdoors. Cuttings of half-ripe wood with a heel, July/August in individual pots in a frame.
Overwinter in a greenhouse for the first winter and plant out in their permanent positions in late spring or early summer.
