Plant description

Small procumbent to erect shrubs, often under 50 cm high. Leaves linear to lanceolate or oblanceolate to 30 mm long and 5 mm wide; silky or softly stellate-tomentose on both surfaces, or with the upper surface scabrous. Flowers yellow to 30 mm across; terminal or on short branches; petals deeply notched. Flowering from August to December. Fruits are brown ellipsoid capsule.

Seed collection and propagation

Collect seeds between October and December. 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.
