Plant description:
Annual herb with erect to ascending branches to 45 cm high with white-woolly hairs. Leaves alternate, linear to lanceolate, to 30 mm long and 2 mm wide, glabrous to hairy, apex blunt to sometimes pointy in upper leaves. Daisy head pale yellow, broadly depressed to depressed-ovoid or globular to 3 cm diameter. Flowers throughout the year but mainly in spring.

Seed collecting:
Collect heads that are matured, pale yellow, a bit spongy and contain brown seeds.
Seed cleaning:
Place the heads in a tray for one to two week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a sieve to separate any unwanted material. Be careful as the seeds are very small. 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 germination:
Seeds are non-dormant, viable seed should germinate readily.
