Plant description

Perennial shrub with many twiggy stems. Upper leaves are linear and lower leaves are narrow-oblong. Flowers are brown-yellow pea flowers at the base of leaves, appearing in winter and spring. Fruits are balloon-like pods with few seeds. Seeds are brown-orange ovoid seeds to 6 mm long, with a large aril at one end. Seed embryo type is investing.

Seed collection and propagation

Collect seeds between December and February. Collect mature pods when turning brown with hard seeds inside. Place the pods in a tray to dry for a week. Ensure the tray is covered with newspaper to prevent the seeds from popping out. Then rub the dried pods carefully 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 (e.g. nicking or softening the seed coat).
