Plant description
Erect annual herb to 16 cm tall, branching at and above base; branches slender, sparsely cottony or glabrous. Leaves alternating up the stems, to 18 mm long and 1 mm wide; flattened cylindrical, sparsely hairy to hairless with blunt or pointed tips. Flower-heads cup-shaped or hemispherical borne singly at the ends of the stems, with orange to yellow papery daisy flowers. Flowering between August and October. Fruits are golden-brown papery daisy-head. Seed embryo type is spathulate.
Seed collection and propagation
Collect seeds between October and December. Collect whole plants that are drying off and turning golden-brown. Each head should have numerous tiny seeds. Place the plant in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a fine sieve to separate the seeds from the 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. Seeds are non-dormant, viable seed should germinate readily.
