Seed collecting:
Collect mature capsules, those turning pale straw colour and containing hard brown seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the 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.
Seed viability:
From two collection, the seed viability were high, ranging from 95% to 100%.
