Seed collection and propagation
Collect seeds between October and May. Collect mature capsules, those turning a brown colour, fat and containing brown seeds. Can collect individual capsules or break off the whole stem. Place the capsules in a tray and leave to dry for 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 95%.
