Plant description

Very small stem-less annual herb to 2 cm high. Leaves in a basal cluster, somewhat succulent, linear and entire or pinnatisect to 2 cm long and 2 mm wide. Daisy flower with white ray florets. Flowering between August and September. Fruits are small brown daisy heads. Seeds are yellow-brown wedge-shaped seed to 2.5 mm long and 1.5 wide, with a cylindrical body and swollen wings with long hairs along the margin. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between October and December. Pick heads that are maturing, drying off, with brown seeds that dislodge easily. Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads 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. From one collection, the seed viability was high, at 95%.
