Plant description

Perennial herb to 30 cm high, with no rhizomes. Stem very short, leaves all radical, sessile, narrowly oblanceolate, entire and sheathing at the base to 60 mm long and 6 mm wide, glabrous. Flowers large white to light purple daisy. Flowering between September and November. Fruits are large daisy heads with numerous seeds, usually turning brown when maturing. Seeds are flat, dark brown, ovoid  to 2 mm long, with serrated wings all around the margin. Seed embryo type is spathulate fully developed.

Seed collection and propagation

Collect seeds between November and January. Pick by hand, mature heads that are turning brown and contain semi-hard, brown seed inside. Place the heads in a tray to dry for 1-2 weeks. Then rub the heads gently by hand to dislodge the seeds. 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. Seed viability is usually high. Seeds are non-dormant, viable seed should germinate readily.
