Plant description

Dense branching shrub to 2 m tall, with few succulent lance-shaped leaves and long spines. Flowers are small and yellow along woody stems. Flowering between August and December. Fruits are deep blue, round fleshy fruit to 20 mm long. Seeds are dark brown ovoid seeds to 6 mm long.

Seed collection and propagation

Collect seeds between October and April. Pick by hand ripe fruits which are soft and deep blue in colour. May have to lift branches to find the fruits. Place the fruits in a bucket of water and rub by hand to remove the flesh. Wash again with clean water and drain. Then place 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 three collections, the seed viability was average to high, ranging from 60% to 90%. This species has physiological dormancy that need to be overcome for the seed to germinate.
