Seeds are yellow semi-flat long ovoid seed to 4.5 mm long and 1 mm wide, surface with parallel striation and hairs and pappus as long as seed. Seed embryo type is spatulate fully developed.
Seed collection and propagation
Collect seeds during November. Collect heads that are fluffy. Either pick off the whole heads or use your finger and pull off the seeds from the head. Mature seeds will come off easily. Place the heads in a tray for a week to dry. No cleaning is required if only pure seeds are collected. If heads are collected, then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be fat and hard. Use a sieve to separate the unwanted material. 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 without any treatment.
