Seed collection and propagation
Collect seeds between November and March. Collect heads that are brown with fluffy white pappus and easily removed with your fingers. If only seeds collected, no further cleaning is required. If whole heads are collected, then place the heads in a tray for a week to dry. Then remove the seeds from the head with your fingers. They should come off easily. 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. Seed viability is usually high. Seeds are non-dormant, viable seed should germinate readily.
