Plant description

Annual herbs to 15 cm high, simple or branched. Leaves elliptic to linear or obovate to oblanceolate, to 30 mm long and 4 mm wide, apex often glassy, scale-like hairs usually present. Flower heads club-shaped or spike-like, to 22 mm long and 7 mm diameter with yellow flowers. Flowering between August and December. Fruits are creamy to pale brown head. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between October and February. Collect heads or whole plants that are pale brown or 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.
