ACACIA triptera 25g

An attractive less well-known Wattle with long curving branches and bright yellow rod-shaped flowers 2.5cm long that occur profusely on long loose spikes during winter and spring.

Blue-green leaves are 8 cm long and 4 cm wide that taper to a point.

Occurs naturally in New South Wales, Queensland and Victoria.

Prefers light well-drained soil on an open sunny position. Drought tolerant and frost resistant once established.

Victoria Conservation code: V - Vulnerable in Victoria: not presently endangered but likely to become so soon due to continued depletion; occurring mainly on sites likely to experience changes in land use which would threaten the survival of the plant in the wild; or, taxa whose total population is so small that the likelihood of recovery from disturbance, including localised natural events such as drought, fire or landslip, is doubtful.

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 the depth of the seed and 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.
