Seed collection and propagation
Collect seeds between September and February. Collect mature capsules, fat, dull green and contain dark, hard seed. Keep a close eye on maturing fruit as it will open and release the seeds quickly. Place the capsules in a tray and leave to dry for a week or two. Capsules will split and release the seeds or you can 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. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
