Seed collection and propagation
Collect seeds between November and January. Collect individual capsules that are turning brown and contain hard seeds or break off whole stems with numerous brown capsules. Place the capsules in a tray and leave to dry for a few week. Then rub the capsules gently with a rubber bung to dislodge the seeds from the capsules. Use a sieve to separate the unwanted material. Some seeds will be empty. Use an aspirator to siphon off the lighter, non-viable seeds from the heavier good seeds. 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. Seed viability is usually low for this species
