Plant description
Annual herb to 15 cm high with very short stems, branching at ground level. Leaves basal and near-basal, not forming a rosette, lobed with 3-9 linear obtuse segments, to 8 cm long. hairless. Flowers small white daisy appearing between June and October. Fruits are hard dense brown daisy heads. Seeds are brown semi-flat pyramid/rocket-shaped seed to 2.5 mm long and 1.5 mm wide, 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. Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads with a rubber bung 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 can be average.
