Plant description

Branching annual herb to 40 cm high with hairless and relatively thick stems. Basal leaves are pinnate or entire. Stem leaves are pinnate to 11 cm long and reducing in size up the stem. Large daisy with white ray florets. Flowering between August and September. Fruits are large brown daisy heads. Seeds are black wedge-shaped curved seed to 3 mm long and 1.5 mm wide, with lobed margins and dense hairs at one end and scattered 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 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 average to high, at 80%. This species has physiological dormancy that needs to be overcome for the seed to germinate. Winter conditions produce high germination. Germination is increased with 250 mg/L gibberellic acid added to water agar. Dormancy can be alleviated with after-ripening at 30 oC or stratification at 15 oC
