Annual herb to 50 cm high with stems erect to ascending, numerous from the base, unbranched, brown, pubescent. Basal leaves narrowly oblanceolate to elliptic, subacute, to 11 cm long, often absent at flowering, stem leaves narrowly lanceolate to linear, acute, to 70 mm long and 5 mm wide, sparsely cobwebby to pubescent, with recurved margins. Flowers loose clusters at end of stalk with reddish-orange to golden-yellow papery daisy flowers. Flowering between July and October. Fruits are yellow-brown daisy head. Seed embryo type is spatulate.
Seed collection and propagation
Collect seeds during January, November. Collect whole heads that are brown or collect seeds that are easily removed from the head. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. 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. Seeds are non-dormant, viable seed should germinate readily.
