Plant description

Tufted, glabrous herbaceous perennial lily to 20 cm high, with long grass-like leaves and with a branching rhizome. Primary inflorescence branches widely divergent, often horizontal but ascending apically, with usually white but also blue or purple flowers. Flowering between October and December. Fruits are pale brown 3-lobed capsules. Seeds are globular black seed to 3 mm diameter with a tuberculate surface. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between December and January. Collect mature capsules, those that are turning a pale straw colour and contain black seeds. Can collect individual capsules or break off the whole spike. 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. From two collection, the seed viability was low to average, ranging from 25% to 40%.
