This variety differ from the other variety found in South Australia, Vallarsia umbricola var. umbricola which have smooth or slightly granular seeds. Flowering between November and April. Fruits are pale brown papery capsule to 11 mm long. Seeds are orange ellipsoid seed to 1.3 mm long and 1 mm wide, with a strongly tuberculated surface.
Seed collection and propagation
Collect seeds between January and May. Collect mature capsules, those that are turning a pale straw colour and contain hard seeds. Can collect individual capsules or break off the whole fruit spike. Place the capsules in a tray and leave to dry for 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. From one collection, the seed viability was high, at 95%.
