Inflorescence slender, solitary, unbranched, frequently leafless in the upper half; scape ending in a terminal raceme with 2–5-flowers. Sepals black, to 3.5 mm long, narrow elliptical, hairy. Petals pink or white, to 4.5 mm long, obovate. Flowering between August and November.

Seed collecting:
Collect mature capsules, those that are fat, hard, turning brown and contain black seeds inside.
Seed cleaning:
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.
