Flowering between July to December.

Brown narrow ovoid capsule to 8 mm long and 4 mm wide, usually shortly beaked.
Seed type:
Light brown cylindrical seed to 3.7 mm long and 1.7 mm wide, covered in scattered hairs and with a large cream appendage.
Seed collecting:
Collect maturing capsules those that are fat, turning a pale brown and contain hard dark seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for a week. Then rub the dried 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.
