Seed collection and propagation
Collect seeds between August and November. Collect mature seed heads that are dried and turning brown by picking off the heads and placing them in a paper bag. Be careful as the heads are spiny. Leave the heads in the paper bag to dry for at least a week. No further cleaning required if only the heads are collected. If other material were collected, use a sieve to separate the unwanted material. Whole heads can be stored 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.
