Plant description
Small erect and spreading shrub to 1 m high with dropping branches covered in dense rusty-coloured hairs. Leaves alternate, oblong-elliptic or obovate, to 8 mm long and 3 mm wide, apex acute but not pungent, upper surface with a few scattered hairs, paler than lower, lower surface hairy, occasionally both surfaces glabrous. Flowers axillary clusters towards tips of short branches with yellow to pale-orange pea-flowers. Flowering between August and December. Fruits are hairy brown ovoid pod to 5 mm long. Seed embryo type is bent.
Seed collection and propagation
Collect seeds between November and January. Collect maturing pods, those that are brown or turning brown and contain hard seeds inside. Place the pods in a paper bag and leave to dry for one to two weeks. Then rub the pods with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. This species has physical dormancy that needs to be overcome for the seed to germinate. The seed coat needs to be ruptured so that water can enter the seed before germination can occur. Methods to rupture the seed coat include scarification with sand paper or nicking the seed coat with a sharp blade or hot water treatment by immersion in boiling water.
