Seed collection and propagation
Collect seeds between October and November. Collect maturing capsules, those that are fat, turning a straw colour and contain hard brown to black seeds or collect whole stems with many maturing capsules. Place the capsules/stems in a tray and leave to dry for one to two weeks. Then rub the capsules/stems gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Be very careful as the seeds are very small. 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.
