Plant description

Erect to spreading, rarely decumbent shrub to 0.6 m high; branches pubescent. Leaves linear, to 16 mm long and 2 mm wide, pubescent to glabrescent; apex obtuse or rounded; margins broad recurved, touching the slightly raised, broader central ridge. Flowers yellow, on pedicels to 25 mm long; terminal but often on short shoots. Flowering between September and December. Fruits are brown hairy capsule with 3 carpels. Seeds are brown ovoid seed to 3 mm long and 2 mm wide.

Seed collection and propagation

Collect seeds between October and February. Collect mature capsules, that are turning a pale straw colour and contain brown seeds. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand 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 genus tends to have low seed viability. From one collection, the seed viability was average, at 65%. This species has morpho-physiological dormancy and can be difficult to germinate.
