ACACIA colletioides

An attractive evergreen shrub with a stiff erect stem with sightly flattened phyllodes (leaves) 2.5 cm long. Large golden yellow flowers occur profusely in clusters from winter to summer.

Victoria Threat status FFG: Endangered (EN)

Occurring naturally in New South Wales, South Australia, Victoria and Western Australia.

Prefers medium to heavy soil in an open sunny position. Drought and frost resistant.

Grow notes:

Although seed can be sown most of the year in many parts of 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.

1. Place the seed in a container and pour in just boiled water and allow to soak overnight.
2. The swollen seed can then be sown, re-treat seeds that have not swollen.
3. Sow the depth of the seed and keep it warm & moist but not wet.
4. Germination should occur in 10-21 days @ 18-22C.

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.
