Plant description

Perennial herb to 40 cm high; stems erect, branched, strigosehirsute, becoming woody at the base only. Base leaves petiolate, oblanceolate, to 7 cm long and 18 mm wide, coarsely serrate. Stem leaves sessile, oblanceolate to cuneate, to 6 cm long and 12 mm wide, acute, entire to shallowly dentate, subamplexicaul at the base, strigose to scabrous. Flower-heads in loose leafy terminal cymes of 4-30 flowers, ray florets yellow. Flowering between May and October. Fruits are brown, dense round spiny fruit-head. Seeds are brown wedge-shaped seed to 2 mm long, with numerous hairy spines at one end. Seed embryo type is spatulate, fully developed.

Seed collection and propagation

Collect seeds between September and December. Collect mature seed heads that are dried and turning brown by picking off the heads and placing them in a paper bag. Be careful as the heads are spiny. Leave the heads in the paper bag to dry for at least a week. No further cleaning required if only the heads are collected. If other material were collected, use a sieve to seperate the unwanted matyerial. Whole heads can be stored 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.
