Plant description

Decumbent to ascending herb with stems to 50 cm high, with scattered long stiff white non-glandular hairs. Basal leaves with 3-lobed, toothed, ovate, to 4 cm long and 3 cm wide, hirsute. Inflorescence in groups of 2-6, rarely solitary, with blue with white or yellow veins flowers. Flowering between July and April. Fruits are long brown capsule to 6 cm long. Seeds are golden brown ovoid seed to 1 cm long, covered in long white hairs and with a 4 cm long hairy awn-like attachment.

Seed collection and propagation

Collect seeds between October and June. Collect matured capsules, those that are turning brown and have exposed brown seeds. Place the capsules in a tray and leave to dry fro 1 to 2 weeks. If only seeds collected, no further cleaning is required. If other material is collected, use a sieve to separate 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. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat). Germination 95%, seed scarified (covering structured removed and seed coat chipped) on 1% w/v agar, 8/16 dark/light, 15°C. See http://data.kew.org/sid
