Leaves are elliptical and leathery, with very fine tips and entire edges, about 8–20 millimetres (0.31–0.79 in) long.

They are white with pink outer sides, about 4–5 millimetres (0.16–0.20 in) in diameter, with about twenty stamens and purple anthers.

Fruits are bright red subglobose berries, about 6–7 millimetres (0.24–0.28 in) in diameter, remaining well into winter.

The branches form roots at nodes when they touch the ground.
