Seed collection and propagation
Collect seeds between October and December. Pick mature capsules when they turn a straw colour and contain hard dark seeds. Place the capsules in a tray and leave to dry for at least a week. Then rub the dried capsules 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 100%.
