Plant description

Shrubs to 2.5 m high. Leaves narrow-ovate or elliptical to 20 mm long and 3 mm wide; upper face convex with mid-rib more prominent than below. Inflorescences 1 or 2 in the axils, uni-flowered or umbellate with 2–4 yellow pea-flowers. This subspecies differs from the other two subspecies found in South Australia in having standard petals all yellow. Flowering between August and November. Fruits are brown asymmetrically triangular pod, beaked with the persistent style. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between September 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).
