Plant description

Annual herb to 8 cm high with several stems arising from the base, either prostrate or erect to 16 cm long. Leaves opposite and alternate; herbaceous to semi-succulent; narrowly elliptical to linear and subterete to 10 mm long and 2 mm wide; densely cobwebby. Flower-heads subglobular to 8 mm diameter with yellow ray-less daisy flowers. Flowering between September and December. Fruits are small dense, dry daisy-heads. Seeds are dark brown, pyramid-shaped achenes to 0.8 mm long, with no pappus. Seed embryo type is spathulate; fully developed.

Seed collection and propagation

Collect seeds between November and February. Collect heads that are hard, drying off and turning pale brown. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Be carefully as the seeds are very small. Viable seeds will be dark and hard. 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.
