Plant description

Multi-stemmed shrub to 2 m tall with ascending, glabrous and angular branches. Leaves linear-elliptic to linear-obovate, to 90 mm long and to 10 mm wide;, dull yellow-green. Inflorescences in axillary clusters with orange-yellow pea-flowers. Flowering between September and November. Fruits are brown asymmetrically triangular pod to 2.5 mm long and 1.7 wide, beaked with the persistent style. Seeds are orange-brown with black mottled reniform seed to 6 mm long and 4 mm wide, with a cream aril. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between November and January. Collect maturing pods that are turning brown with hard seeds inside. Leave the pods in a paper bag to dry for at least a week. Rub the pods gently with a rubber bung to dislodge the seeds. Use a sieve to separate the seeds from unwanted material. Store the dried fruit heads with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 95%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat)
