An attractive Acacia with a graceful weeping habit and blue grey triangular shaped foliage. Golden yellow ball-shaped flowers in spring.
The common name Knife leaf wattle is derived from the shape of the foliage.
Endemic to New South Wales and Queensland.
A hardy plant that prefers a well-drained soil in a sunny position. Tolerant of frost, drought and poor soils.
Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn in temperate climates, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C.
Acacia seeds germinate readily, however they do have a hard outer coating which is impervious to water and generally germination will normally not occur unless the seed is scarified by abrading or pre-treated with boiling water first.
General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
