Seed collecting:
Collect capsules that are maturing, drying and turning pale brown with dark seeds inside. Keep an eye on the capsules as they can ripen and split open quickly.
Seed cleaning:
Place the capsules in a tray and cover with paper to prevent seeds popping out and leave to dry for a week. Then rub the capsules gently  with your hands 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.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate.
