Plant description

Decumbent annual herb with stems to 40 cm long. Leaves basal and on flower stems, alternate, sessile or shortly petiolate, oblanceolate to narrow-oblong, basal leaves to 3 cm long and 0.4 cm wide. Flowers white to pale-pink, appearing between August and October. Fruits are red-brown narrow-ovoid to elongate-cylindrical capsule to 5 mm long with 3-valves. Seeds are shiny black reniform-ovoid seed to 1 mm long and 0.7 mm wide, with a smooth surface. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between September and December. Collect mature capsules that are turning a red-brown colour and contain dark 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. From one collection, the seed viability was high, at 80%.
