Seeds are dark brown reniform seed to 3 mm long and 2 mm wide, covered in long white hairs. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between January and December. Collect capsules that are drying off and starting to turn brown. The seed inside should be brown and hard. Place the capsules into a tray and leave to dry for a week. Then rub the capsules 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 two collections, the seed viability was high, at 100%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
