Seeds are brown cone-shaped seed to 3 mm long, surface with small barb, one curved spine at the swollen end. Seed embryo type is spatulate fully developed

Seed collection and propagation

Collect seeds between October and January. 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. From one collection, the seed viability was average, at 55%. Seeds are non-dormant, viable seed should germinate readily.
