Bright yellow flowers spheres borne in simple racemes about 30 mm long with a pleasantly sweet fragrance that arise near and at the ends of branchlets.
The weight of the flowering causes the outer branches to become pendulous, flowering is prolonged and prolific, extending from the end of July through winter to early October.

Native to the tablelands of southern Queensland and northern New South Wales.

Prefers medium to heavy soils in an open sunny position. Frost resistant but drought tender. Suitable to areas with high annual rainfall and winter frost.

Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn, 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 seed keep 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.
