Plant description

Broom-like shrub to 1 m high with rigid, terete and striate branchlets to 2 mm thick, glabrous. Juvenile leaves occasionally present; 2 lobed to hatchet-shaped, to 30 mm long and 10 mm wide, fleshy. Phyllodes reduced to spines, regularly spaced, to 5 mm long; terete, pungent, oblique to branches. Inflorescences axillary with solitary or clusters of pink-apricot to brown-red pea-flowers. Flowering between August and October. Fruits are dark brown asymmetrically triangular pod to 15 mm long and 10 mm wide, with one seed inside. Seeds are orange-brown with black mottled reniform seed to 4 mm long and 2 mm wide, and a cream aril. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between October and December. Collect maturing brown seed pods from the plant using secateurs or by hand. Plant is prickly so it is advisable to wear gloves. 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. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
