Plant description

Erect or ascending annual herb to 45 cm high with numerous stems arising from the base, covered in cobwebby to white-tomentose hairs. Leaves alternate, flat, oblanceolate, to 5 cm long and 5 mm wide, cobwebby, greyish-green. Flower-heads ellipsoid to narrow-ovoid, to 50 mm long and 11 mm diameter with yellow ray-less daisy flowers. Flowering between August and December. Fruits are dense, dry daisy-heads. Seeds are light brown, pyramid-shaped achenes to 0.6 mm long, with 2 or 3 bristles. Seed embryo type is spathulate fully developed.

Seed collection and propagation

Collect seeds between October 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. Seed viability is usually high. Seeds are non-dormant, viable seed should germinate readily.
