Plant description

Shrub to 5 m high with pendulous, wiry, glabrous, green and striate branches. Juvenile leaves 1–3-foliolate, leaflets oblong to linear-lanceolate, to 4 cm long, mature leaves reduced to slender petioles to 25 cm long. Flowers in racemes to 20 cm long with yellow to orange often with red blotches pea-flowers. Flowering between November and February. Fruits are black ovoid pod to 5 mm long, with one seed inside. Seeds are mottled orange-red, reniform seed to 2.5 mm long and 2 mm wide. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between January and April. Collect maturing pods, those that are fat, turning black and contain a hard orange seed inside, by running your hands along the fruit-spikes. Place the pods in a tray and leave to dry for 1 to 2 weeks. Then rub the dried pods to dislodge the seeds. Use a sieve to separate any 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. From two collections, the seed viability were high, at 100%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
