Seed collecting:
Collect mature fruits, those that are fat and turning red with brown seeds inside or collect capsules that are brown and dried.
Seed cleaning:
If fruits are fresh, break open the fruits and wash the content in water. Drain the liquid leaving behind the seeds. Place the wet seeds onto paper towels and leave to dry. If fruits are dried, rub the fruits with a rubber bung 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.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
