Seed collection and propagation

Collect seeds between October and January. Collect maturing capsules that are fat, turning orange-brown in colour, have not open and contain hard black seeds. Place the capsules in a tray and leave to dry for one to two weeks to split. Rub the capsules gently with a rubber bung 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 90%.
