Small herb with a vertical stolon 2-8 cm long; leaves in a flat rosette; lamina sessile spatulate, 15-35 mm long, 5-15 mm wide. Scapes 1 to many, 2-5 cm long, 1-flowered, white. Flowering all months but especially May-November. Fruits are red-brown ovoid to globose capsule to 8 mm diameter. Seeds are black angular ovoid-cylindrical seed to 1.5 mm long, with a mesh-like surface.
Seed collection and propagation
Collect seeds between October and December. Collect mature capsules, those that are fat, hard, turning brown and contain black 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. 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 100%.
