Seed collection and propagation

Collect seeds between October and December. Collect mature capsule, those that are drying off, turning brown and contain dark, hard seeds inside. Can collect individual fruit cluster or break off whole heads. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the fruits 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.
