Seed collection and propagation

Collect seeds between February and April. Collect heads that are fat, hard and turning brown by picking off the whole heads. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands or a rubber bung to dislodge the seeds. Viable seeds will be fat and hard. 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.
