Seed collection and propagation

Collect seeds between August and November. Collect matured capsules, those that are turning brown and have exposed brown seeds Place the capsules in a tray and leave to dry fro 1 to 2 weeks. If only seeds collected, no further cleaning is required. If other material is collected, use a sieve to separate 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 This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
