Plant description

Dioecious perennial tussock herb with bright green rigid leaves with 3 tiny points at the tip, to 60 cm long; basal sheaths becoming fibrous. Flower white. Flowering between August and November. Fruits are ovoid to globular capsule to 6 mm long; smooth, truncate at the summit, sometimes slightly curved. Seeds are yellow-brown, rounded wedge-shaped seed to 6 mm long and 3 mm wide. Seed embryo type is linear, underdeveloped.

Seed collection and propagation

Collect seeds between November and December. Collect mature fruits, turning brown with a hard seed inside, or when they are starting to split. 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 collections, the seed viability was high, at 100%. This species has morpho-physiological dormancy and will germinate slowly over weeks to months.
