Seed collection and propagation
Collect seeds between August and December. Collect heads that are large, fat, 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. From one collection, the seed viability was very low, close to 0%. This maybe due to timing of seed collection (too early before seed is fully developed. Seeds are non-dormant, viable seed should germinate readily.
