Seed collection and propagation
Collect seeds between January and December. Collect seed-heads that are brown and come off easily with your fingers. Place the seed-heads in a tray to dry for a week. Then rub the heads by hand and use a fine sieve to separated the unwanted material. Be careful as the seeds are very small. Seeds are orange brown 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 high, at 100%. Seeds are non-dormant, viable seed should germinate readily.
