Various communities and soils. Prefers dry shallow soils in higher rainfall areas or heavier soils in lower rainfall areas. Tolerates limited inundation, extended dry periods, alkaline and acidic soil. Frost tender when young. Prefers 300 – 550 mm rainfall in the Riverina.

Collect early Dec-mid Jan, seeds released quickly. Propagate from scarified seed (±75 viable/gram), soak in boiling water before sowing. Regenerates from seed after disturbance, readily established when direct seeded.

Useful low-level windbreak cover where it doesn’t spread. Controls soil erosion due to fibrous roots, improves soil fertility (legume). Excellent habitat and refuge for small birds due to prickliness. Flowers provide food for insects, attracting insect-eating birds. Seeds eaten by birds. Attractive ornamental for hedges, barriers, screening, and as cut flower.
