ACACIA pentadenia

A graceful medium-sized shrub with an erect slender habit forming a dense crown. A spectacular display of yellow flowers in paired balls occurs from spring to summer.
The leaves (phyllodes) are feather-like and divide into 2 and 5 pairs each with 20 to 30 pairs of tiny leaflets.

Endemic to the Karri forests of Western Australia.

Ideally suited to temperate climates. Prefers a sheltered semi-shade position in a medium to heavy soil. Drought and frost tender.

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 that 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 seed 3-4mm deep, keep warm & moist but too 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.
