A fast-growing tropical Acacia often with a straight trunk that can grow to 30 meters in height in ideal conditions.

Flowers occur profusely in a spectacular display of pale yellow rod-shaped blooms from March to July in its native range. 
Widely used site rehabilitation and commercial for its timber.

Adaptable to a range of soil and is tolerant to low fertility soils with impeded drainage but prefers fertile sites with good drainage. 
Occurs naturally in Northeastern Queensland and the Western Province of Papua New Guinea and the Eastern Maluku Islands.

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, avoiding 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 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.
