Tufted, glabrous herbaceous perennial lily with long grass-like leaves to 50 cm long and 15 mm wide, sheath often papery. Flowers lilac-blue to deep-blue along a long spike. Flowering between August and October. Fruits are pale brown 3-lobedcapsule to 8 mm in diameter. Seeds are globular black seeds 2 mm in diameter with fine irregular low tubercles. Seed embryo type is linear fully developed.
Seed collection and propagation
Collect seeds between October and December. 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. Seed viability can be low. High germination rates after 4 weeks cold stratification at 5oC and sown April (pers. comm. Shaun Kennedy - SA Water) - see seedling images on Sosa webpage.
