Small shrub covered in short velvety and long spreading hairs. Leaves heart-shaped, to 8 cm long covered in velvety hairs, margins coarsely toothed. Inflorescence tubular with yellow flowers, turning white when dried. Flowering throughout the year. Fruits are brown capsule to 15 mm diameter with up to 10 angles. Seeds dark brown, kidney-shaped to 3 mm long and 2 mm wide, covered in short scattered hairs. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between January and December. Collect mature capsules, those that are turning pale straw colour and contain dark hard seeds. Place the capsules in a tray and leave to dry for 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. Seed viability is usually high. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
