Plant description

Prostrate, succulent perennial plant with stems to 1 m long or more and 11 mm diameter. Leaves to 10 cm long and 11 mm thick, usually distinctly incurved, green to glaucous, usually thicker than wide near the middle with faces usually slightly convex. Flowers large, daisy-liked, light purple merging to white at and near base. Flowering between August and October. Fruits are fleshy, plump red globular fruit to 25 mm long, slightly compressed. Seeds are semi-flat reniform brown seed to 1.5 mm long and 0.8 mm wide. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between November and January. Collect mature fruits, those that are fat and turning red with brown seeds inside. Break open the fruits and wash the content in water. Drain the liquid leaving behind the seeds. Place the wet seeds onto paper towels and leave to dry. 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. Seed viability is usually high. Seeds are non-dormant, viable seed should germinate readily without any treatment.
