Plant description

Small erect shrub to 150 cm high. Leaves linear-oblanceolate to linear, to 30 mm long and 2 mm wide; glabrous or covered by curly hairs. Flowers yellow to 8 mm long, axillary or terminal on short shoots. Flowering between July and September. Fruits are brown ellipsoid capsule with 3 carpels and 2 ovules in each; glabrous. Seeds are brown, globular seed to 2 mm diameter.

Seed collection and propagation

Collect seeds between October and January. Collect mature capsules, those 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 tend to have low seed viability. This species has morpho-physiological dormancy and can be difficult to germinate.
