Plant description

A decumbent and branching perennial herb usually forming compact clumps with thick fleshy leaves. Flowers are white daisies displayed above the foliage. Flowering throughout the year. Fruits are brown daisy-head to 1 cm across containing numerous brown seeds. Seeds are flat ovoid brown seeds to 2 mm long and 1.3 mm wide, with few hairs and a serrated margin. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between January 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%. This species may have physiological dormancy that needs to be overcome for the seed to germinate.
