Seed collection and propagation
Collect seeds between September and February. Collect by hand fruits that are orange in colour, opened or unopened. Place the fruit in a tray and leave to dry for at least two weeks. The fruit will split and open as it dries. Once the fruits split, use your fingers or a small spoon to extract 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. From one collection, the seed viability was high, at 100%.
