Plant description

Upright straggly perennial herb or subshrub to 100 cm tall, covered in velvety hairs. Leaves ovate to lanceolate, to 7 cm long. Flowers creamy yellow or pale yellow, scarcely exceeding the calyx. Flowering possible all year round depending on rainfall. Fruit capsule nearly as long as the calyx comprising of 7-10 segments which open at an acutely pointed tip.  Seeds are dark brown covered in hairs. Seed embryo type is folded.

Seed collection and propagation

Collect seeds possibly all year round depending on rainfall. 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. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
