A large shrub to 4 m high and 2 m wide, found in a limited distribution in coastal regions, in central and southern New South Wales. It is restricted to the area between Bargo in the north out to Goulburn in the east and down to around Nowra in the south; it is still considered to be rare.
It grows in sandstone and in clay soils, as a part of dry sclerophyll woodland and forest communities.
It has smooth brown to grey-green often mottled bark,
Leaves are compound-bipinnate (Jacaranda-type) to about 8 cm long, with pinnae (groups of leaflets or pinnules) to 4 cm long, with each pinnule about 6 mm long and 2 mm wide.
Flowers are produced in globular heads, to 8 mm in diameter, with up to 15 very small, staminate flowers in each head. Heads are produced on axillary racemes up to about 25 heads, yellow to bright yellow and occur in July to October.
Seed pods are straight to slightly curved to 7 cm long and 8 mm wide.
An adaptable plant in most soils but prefers a protected position with some moisture. It is also frost resistant.
Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.
Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.
Most wattles regenerate from seed after fire, with some species exhibiting basal suckering.
Acacia – from Greek acis, meaning a thorn or “thorny”.
