Plant description

Annual herb to 25 cm high with erect, hairless stems. Leaves basal and near-basal, not forming a rosette, pinnatisect with 3-7 linear obtuse segments, or the lower ones entire and linear to 6 cm long, glabrous. Flowers white on a long stalk. Flowering between July and September. Fruits are hard dense daisy-head. Seeds are black wedge-shaped curved seed to 2.5 mm long and 1 wide, with smooth faces and woolly hairs along the margin. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between September and November. 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. From two collections, the seed viability was high, ranging from 95% to 100%.
