Plant description
Herb with short rhizome; roots fleshy. Leaves obovate to spathulate to 80 mm long and 20 mm wide; sinuate to toothed with acute or obtuse teeth, sparsely to quite densely hairy. Flower-heads solitary on long slender stalk to 20 cm long, often darkly pigmented, with white to purple daisy-flower. Flowering in Spring and summer. Fruits are brown head with exposed seeds. Seeds are semi-flat brown, ovoid seed to 4 mm long and 1 mm wide. Seed embryo type is spathulate.
Seed collection and propagation
Collect seeds between October and January. Pick heads that are maturing; drying off, with exposed brown seeds. Mature seeds should come-off easily. Place the heads in a tray and leave to dry for a week. Then gently rub the heads by hand to dislodge the seeds. Use a sieve to separate the unwanted material. 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. From two collections, the seed viability was high, ranging from 90% to 95%.
