Plant description

Annual herb to 20cm tall or sprawling; glabrous or sparsely cottony. Leaves alternating up the stems, to 16 mm long and 1mm wide; cylindrical, sparsely hairy to hairless; tips blunt. Flower-heads bell- or funnel-shaped becoming hemispherical;borne singly at the end of the stems with yellow daisy flowers. Flowering between August and October. Fruits are dense yellow or pale-brown papery head. Seed embryo type is spathulate.

Seed collection and propagation

Collect seeds between October and January. Collect heads or whole plants that are drying off and turning brown. Each head should have numerous tiny seeds. Place the heads 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.
