Seed collection and propagation
Collect seeds between April and June. Collect mature capsules that are fat, turning a pale straw-colour and containing brown seeds. Can be time consuming to find mature capsules. Can collect individual capsules or break off whole stem. Place the capsules in a tray and leave to dry for one week. Rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Be 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 From one collection, the seed viability was high, at 100%.
