Plant description

Robust decumbent herb to 20 cm tall. Leaves 3 to 10 cm long and 24 mm wide, broad, leathery and easily recognisable even when not in flower. Inflorescence spike with 1-5 large bright pink flowers. Flowering between May and August. Fruits are pale brown box-like capsule to 25 mm long. Largest of any Australian Wurmbea. Seeds are orange brown globular seed to 2 mm diameter. Seed embryo type is linear under-developed.

Seed collection and propagation

Collect seeds between August and October. Collect mature capsules, those turning pale straw colour and containing hard brown seeds. Place the capsules in a tray and leave to dry for 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%.
