Seed collection and propagation
Collect seeds between October and December. Collect whole plants that are drying off, turning red-brown with mature fruit-spikes. These will contain very small brown seeds when rubbed with your fingers. Place the plants in a tray and leave to dry for two weeks. Then rub the plants gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Be very careful as the seeds are very small. 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%.
