Plant description

Dense perennial shrub to 2 m tall but on the coast, often stunted to less than 50 cm, with thick, smooth, green and shiny lance-shaped leaves arranged opposite to each other. Flowers are white and tubular, with five petals arranged almost at right angles to each other. Flowering between October and February. Fruits are round fleshy red berries to 10 mm across. Seeds are yellow woody elipsoid seed to 10 mm across.

Seed collection and propagation

Collect seeds between December and April. Collect berries that are red or turning red. Place the fruits in a bucket of water and rub the flesh off the fruits with your hands then rinse and drain leaving just the clean seeds behind. Place the seeds on paper towels and leave to dry overnight. 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 80%. This species has a combination of physical (hard seed coat) and physiological dormancies that needs to be overcome for the seed to germinate.
