Seed collection and propagation
Collect seeds between August and December. Collect mature fruits either by breaking off individual spikes or by removing plants that are drying off with fruits that are purple to straw-colour and seed segments coming apart easily. Place the fruit spikes in a tray and leave to dry for 1 to 2 weeks. Then rub the dried fruit spikes with a rubber bung to dislodge the seeds. Use a sieve to separate any 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.
