Seed collection and propagation

Collect seeds between September and December. Collect capsules that are maturing, fat and turning brown and contain hard dark seeds. Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Seeds should be hard and brown. 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.
