Seeds are dark brown, pyramid-shaped achenes to 0.8 mm long, with no pappus. Seed embryo type is spathulate fully developed.
Seed collection and propagation
Collect seeds between November and February. Collect heads that are hard, drying off and turning pale brown. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Be carefully as the seeds are very small. Viable seeds will be dark 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.
