Seed collection and propagation
Collect seeds between November and January. Collect capsules that are maturing, turning brown, easily split open and with black seeds inside. Place the capsules in a tray and leave to dry for a week. Then rub the capsules with your hands 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. From two collections, the seed viability were high, at 100%.
