Breynia oblongifolia, commonly known as coffee bush, grows naturally in Australia and New Guinea as shrubs up to 3 m (10 ft) in height. The species produces alternate, ovate leaves 20–30 mm (0.8–1.2 in) long. Small, green flowers are produced in spring and summer, and these are followed by orange or pink berries about 6 mm (0.24 in) diameter that turn black when fully ripe.
