Flowers terminal, blue, sometimes pink or white, funnel-shaped with 5 narrow-triangular lobes which are less than twice as long as the base. Flowers throughout the year. Fruits are brown globular, cylindrical or sometimes conical capsule to 9 mm long, swollen in appearance. Seeds are tiny orange elliptic seed to 0.6 mm long and 0.3 mm wide. Seed embryo type is spatulate under-developed.
Seed collection and propagation
Collect seeds between January and December. Collect capsules that are maturing, drying and turning orange with hard seeds inside. Place the capsules in a tray 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. Be careful as the seeds are very small. 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 low, at 30%.
