Plant description

Prostrate or spreading perennial herb to 50 cm diameter; the whole plant glabrous except for the youngest parts. Leaves opposite and/or alternate, semi-succulent, oblanceolate to obovate to 15 mm long, obtuse. Flowers in terminal, or less often, leaf-opposed clusters. Perianth segments white or with a pinkish tinge. Stamens 15�20 with a few staminodes; carpels 3 or 4; styles 3 or 4. Flowers possibly all year round. Fruits are brown capsules. Seeds are shiny red-black, reniform seed to 1.2 mm long and 0.7 mm wide, with striated surface. Seeds larger than in the other two species. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between January and December. Collect capsules that are maturing, turning brown and contain hard, brown seeds inside. 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. Be careful as the seeds are very small. 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 average, at 70%. This species has physiological dormancy and can be difficult to germinate.
