Seeds are dark red-brown reniform seed to 0.5 mm diameter, coppery lustre at maturity with a warty surface. Seed embryo type is peripheral.
Seed collection and propagation
Collect seeds between October and January. Collect mature capsules, those 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 three collections, the seed viability was high, ranging from 85% and 100%.
