Seed collection and propagation

Collect seeds between September and December. Pick heads that are maturing, drying off, with brown seeds that dislodge easily. Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads 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.
