FABACEAE

I. a. subsp. australis

Open, erect, spreading shrub to 2.5 m high, long slender stiff stems. Mauve to purple (sometimes white) pea-like flowers, winter-spring.

Woodland and eucalypt forest, commonly in hilly areas. Prefers poor, shallow soil in semi-shade or dappled shade. Tolerates moderate frost and extended wet periods, adapts to well-drained acidic soils. Prefers 300 – 500 mm rainfall in the Riverina.

Propagate from scarified seed (soak in boiling water, then dry) or cuttings. Germination takes 3-4 weeks, direct seed into pots (2-3 seeds/pot). Regenerates easily from seed, especially after fire.

Low-level windbreak cover. Improves soil fertility (legume). Excellent habitat, flowers provide pollen and nectar for insects, food for butterfly caterpillars. First Nations used roots for fish poison. Attractive ornamental, best planted in groups. Tip prune to promote bushiness. Leaves and stems produce yellow-fawn dye.
