Seed collection and propagation
Collect seeds between July and February. Collect individually or break off short fruiting stems with fat capsules with hard dark seed. Green capsules can be collected if the seeds are dark and hard. Place the capsules in a tray and leave to dry for one to two weeks. Then gently rub the capsules with a rubber bung to dislodge the seeds. Use a sieves 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.
