Plant description

Slender shrub to 1 m high with stems glabrous and minutely tuberculate to densely hairy with erect hairs. Leaves alternate, opposite or in regular whorls of 3–5, narrow-elliptic to orbicular, to 20 mm long and 15 mm wide, acute or obtuse, margins flat to revolute, usually undulate, both surfaces glabrous or with a few fine, erect hairs particularly near margins. Inflorescences in group of 1–3 deep lilac-pink or occasionally white bell-shaped flowers, sepals broad-ovate with upper part strongly reflexed, petals obovate, ovary velvety. Flowering between August and November. Fruits are brown broad ovoid capsule to 8 mm long. Seeds are brown ovoid seed to 4 mm long and 2 mm wide, covered in long hairs and with a cream appendage.

Seed collection and propagation

Collect seeds between October and January. Collect maturing capsules those that are fat, turning a pale brown and contain hard dark seeds. Place the capsules in a tray and leave to dry for a week. Then rub the dried 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.
