Tufted herb to 70 cm high forming clumps or large colonies. Leaves in fan-shaped clusters of 4-10, linear, to 55 cm long and 10 mm wide; glabrous, except margin sometimes with brown hairs. Inflorescence a single blue-violet flower at the tip of a stalk that is longer than the leaves. Flowering between October and December. Fruits are long brown cylindrical capsule to 2.5 cm long. Seeds are brown compressed-ovoid seed to 3 mm long and 1.2 mm wide. Seed embryo type is linear under-developed.
Seed collection and propagation
Collect seeds between December and March. Collect mature capsules, those that are drying off and turning brown with hard brown seeds inside. 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%. Seeds are non-dormant, viable seed should germinate readily.
