Seed collection and propagation
Collect seeds between February and March. Collect plump capsules as they start to dry and turn brown. Pods will split and release the seeds quickly however and will require monitoring. To increase the chances of collecting mature pods it is recommended that a small breathable bag (ie. Organza) to be used to enclose the developing capsules. Place the capsules in a container that will hold fine seeds and leave to dry for a few weeks or until the capsule split. Then carefully hold the capsule and tap it gently to release the seeds. 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, refrigerator or liquid nitrogen.
