Seed collection and propagation
Collect seeds between February and March. Collectplump 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. A total of 1.13g (350,000 seeds) were collected by Cath Dickson in 2016 from the Naracoorte area. The sample contained 22 scapes which included a total of 71 pods.
