Plant description

Grass-like lily with narrow, linear flat leaves to 60 cm long and 4 mm wide. Flowers white with a reddish centre arise in clusters (umbels) of 2-10 flowers on a slender stalk with two leaf-like bracts. Flowering bewteen July and October. Fruits are pale brown papery ovoid capsule to 15 mm long. Seeds are brown seed to 3 mm long. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between November and January. 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. From one collection, the seed viability was high, at 100%.
