Plant description

Erect, many-stemmed annual herb to 30 cm high, hairy. Basal leaves petiolate, to 13 cm long; pinnately lobed, the lateral lobes linear to toothed; stem leaves reducing to entire, sessile. Inflorescence a dense elongated spike with white flowers. Flowering between June and October. Fruits are long hairy, brown pod to 19 mm long and 1.6 mm wide. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between September and December. Collect maturing pods, turning pale brown with hard seeds inside. Be gentle with the pods as they split open easily. Place the pods in a tray and cover with paper to prevent seeds from popping out and leave to dry for a week. Then rub the dried pods gently 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.
