Seed collection and propagation

Collect seeds between September and January. Pick by hand mature heads that are turning brown and contain semi-hard brown seed inside. Place the heads in a tray to dry for 1-2 weeks. Then rub the heads gently by hand to dislodge the seeds. Use a sieve to separate the 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. Seeds are non-dormant, viable seed should germinate readily.
