Erect or spreading tree, 5-12 m high. Greyish bark and sickle-shaped ‘leaves.’ Pale yellow to almost white flowers, Dec-Apr. Very long-lived, moderate growth rate.

Occurs in various vegetation communities. Prefers well-drained soil, including shallow dry soil in hill country. Tolerates frost, fire, drought, and wind. Dislikes poorly-drained soil. Prefers 300 – 500 mm rainfall in the Riverina.

Collect mid-spring to autumn, seeds mature in ~11 months and drop quickly. Propagate from scarified seed (±28 viable/gram), soak in boiling water before drying and sowing. Regenerates by root suckering, from soil-stored seed after disturbance, and from cut stumps.

Useful medium-level cover in windbreaks, fair shade, and resistant to livestock damage. Excellent for erosion control and soil fertility improvement (legume). Valuable habitat for insects, birds, and other wildlife. Timber similar to Blackwood, suitable for furniture and turning. First Nations used for fibre, fish poison, medicine, and woomeras. Attractive ornamental tree for gardens and rockeries. Leaves produce yellow or brown dye.
