Seed collection and propagation

Collect seeds between August and November. Collect heads or whole plant that are drying off and turning brown. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be long, 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. Seeds are non-dormant, viable seed should germinate readily.
