Seed collection and propagation
Collect seeds between October and February. Lift branches carefully to locate the fruits at the base of the plant. Collect berries that are dark-purple and soft with a hard seed inside. Place the berries in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required to remove all the flesh. Then spread the wet seeds on some paper towel and leave to dry. 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 average, at 65%. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
