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 two collections, the seed viability were high, at 100%.
