Seed collection and propagation
Collect seeds between March and June. Collect heads that are matured,golden brown and contain brown seeds. Place the heads in a tray for one to two week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a sieve to separate any unwanted material. Viable seeds will be small and brown. 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.
