Plant description

Robust perennial herb to 90 cm high with numerous thick pithy stems to 8 mm diameter. Leaves linear to narrow-lanceolate to 30 mm long and 3 mm wide, tapering gradually to the tip; often deciduous. Inflorescence of terminal clusters with 31 pale yellow to cream flowers. Flowering between August and December. Fruits are cream to reddish-tinged papery ovoid fruit to 6.5 mm long with 3 longitudinal wings.

Seed collection and propagation

Collect seeds between October and January. Collect fruit that have developed wings and the seed in the middle is hard. Place the fruit in a tray and leave to dry for a week or two. Seeds can be stored with the wings or you can rub the dried fruit with a rubber bung to dislodge the seeds. Use a sieve to separate any 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 95%.
