Plant description
Erect shrub to 150 cm high; branchlets pubescent. Leaves spreading and recurved, heart-shaped, to 7 mm long and 8 mm wide; flat to slightly convex, margins entire to minutely serrate. Inflorescence in axillary spikes to 3.5 mm long, with 1-3 white tubular, densely-bearded flowers. Flowering possibly throughout the year. Fruits are ovoid fleshy fruit to 5.6 mm long and 4.3 mm wide; smooth. Seed embryo type is linear, under-developed.
Seed collection and propagation
Collect seeds between July and November. Collect berries that are white with a hard seed. Place the berries in a bucket of water and leave to soak over night. Rub the flesh off by hand. Drain and wash again if required to remove all the fleshy parts. Then spread the wet seeds onto paper towels 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. This species has morpho-physiological dormancy and is difficult to germinate.
