An unusual low growing Acacia (typically 30 to 60 cm) that is commonly known as the Grass Wattle as it produces grass or rush like phyllodes (leaves)

Flowers occur as creamy-yellow to deep yellow balls either singly or in pairs from the months of May to October but mainly June to September in its natural range.

Occurs naturally in the South-West Province of Western Australia.

Prefers a light to gravelly soil in a well-drained open sunny position.

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.

  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.
