Site Preference:
Well-drained soil in semi-shade. Tolerates moderately heavy frosts.
Flowering:
Rose-pink, late winter-spring. Short flower sprays.
Seed Collection:
Mid Nov to early Feb. Monitor closely as seeds shed immediately or very soon after maturity. Ensure collection by securing nylon stockings or paper bags to fruiting branches after flowering.
Propagation:
From scarified seed or cuttings, which strike readily. Pour boiling or very hot water over seeds and soak until water cools. Dry to prevent rotting and sow. Germination takes 3-4 weeks. Suitable for direct seeding in pots (2-3 seeds per pot).
Regeneration:
From seed, particularly after fire.
VALUES:
Shade & Shelter:
Useful low-level cover in windbreaks.
Land Protection:
Legume — improves soil fertility by ‘fixing’ nitrogen.
Wildlife:
Excellent habitat. Flowers are a pollen and nectar source for many native insects, including bees and wasps. Food for butterfly caterpillars.
Ornamental:
Attractive ornamental for gardens. Prune from early age to promote bushiness and prevent straggliness.
