Plant description

Small shrub with stem almost totally subterranean and branched under ground. Leaves forming an erect tuft, depressed obtriangular, or often concave in cross-section, to 3.5 mm wide and 1.5 mm thick, green, not glaucous. Inflorescence with flower-bearing part to 30 cm long and 25 mm diameter with numerous flowers, with the inner tepals yellow.. Flowering between October to November. Fruits are numerous woody capsules maturing to dark brown along the spike. Capsule split into three segments, each containing one black seed. Seeds are flat pyramid-like black seed to 9 mm long and 5 mm wide. Seed embryo type is linear under-developed.

Seed collection and propagation

Collect seeds between December and February. Cut off fruit spikes that have mature capsules, usually turning dark brown or beginning to split. The seeds inside should be black. Place the fruit spikes in a tray or bucket and leave to dry for 3-4 weeks or until most of the capsules split. Then shake the fruit spike in a bucket to dislodge the seeds. 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 on collection, the seed viability was high, at 90%. Seeds are non-dormant, viable seed should germinate readily without any treatment.
