Plant description

Erect herb to 100 cm high with glabrous stems. Leaves oblong to oblanceolate, to 69 mm long and 17 mm wide, bright green, glabrous or with sparse hairs, margins denticulate to dentate with 5–13 pairs of teeth, apex obtuse or acute, base cuneate to obtuse. Flower-heads in small terminal panicles with small white-cream daisy flowers. Flowering likely synchronised to rainfall events. Fruits are small golden brown heads. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between January and December. Collect heads that are drying off and turning brown. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands or a rubber bung to dislodge the seeds. Use a sieve to separate 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.
