Plant description

Iron grass with rigid glaucous leaves to 60 cm long and 4 mm wide. Male and female flowers occurring on the same plant (monoecious). Male flowers with pedicels to 4 mm long; females sessile. Clusters of flowers grow along an erect spreading panicle to 30 cm long. Fruits are ovoid to globular capsule to 6 mm across; dark purple-black when mature. Seeds are yellow to brown, rounded wedge-shaped seed to 5 mm long and 3 mm wide. Seed embryo type is linear, underdeveloped.

Seed collection and propagation

Collect seeds between December and January. Collect mature fruits, turning purple-black 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 three collections, the seed viability was high, at 100%. This species has morpho-physiological dormancy and can take several weeks to germinate. Germination was enhanced by treatment with diluted smoke water.
