Plant description

Hairy, perennial herb with a cluster of basal leaves. Leaves elliptic to spathulate, to 10 cm long, green with silky hairs on both surfaces. Inflorescence round head on a long stalk to 30 cm high, with mid to deep blue flowers. Flowering between October and December. Fruits are pale brown round heads with numerous shuttle-cock like seeds. Seeds are brown seed to 3 mm long. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between December and February. Collect mature capsules, those that are turning a pale straw colour and contain brown seeds. Can collect individual capsules or break off the whole head. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules 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. Seed viability is usually high.
