Coprosma rotundifolia aka Coprosma Rotundifolia

Coprosma rotundifolia is an evergreen shrub from New Zealand. Its native range includes Stewart Island and both main islands. It belongs to Rubiaceae, the coffee family. Kew lists its growth form as a shrub or tree. Plants For A Future gives a height of about 8 feet [2.4 metres]. It keeps its leaves through the year. In the wild, it grows in woodland across both main islands. It often grows on alluvial soils, which rivers have laid down.

Wind carries pollen between its flowers. Male and female flowers grow on separate plants. The species does not set seed through self-pollination. Grow both sexes together when seed or fruit is wanted. The red fruit measures about 0.2 inches [5 millimetres] across. People can eat the fruit raw or cooked. It tastes sweet, though its flavour is mild. Roasted seeds can serve as a coffee substitute. Plants For A Future gives its food value a low rating. That source lists no known hazards, but this is not a full safety assessment.

Choose moist soil that drains very well for garden plants. A neutral to slightly acid soil suits it best. Sandy and loamy soils suit it, though it accepts most soils. It can grow in full sun or light shade. A woodland garden offers a suitable setting in a mild climate. Other suggested sites include sunny woodland edges and spots near south- or west-facing walls. Plants tolerate hard pruning and clipping. They can also cross freely with other members of the genus. Frost can harm this species. In Britain, outdoor planting is best limited to the mildest areas. Plants For A Future lists USDA zones 8–11.

Seed and autumn cuttings offer ways to raise new plants. Sow ripe seed in a greenhouse or cold frame. Stored seed can be sown in spring in a cold frame. Germination may take more than a year, even with fresh seed. Move seedlings into separate pots once large enough to handle. Keep young plants under glass through their first winter. Plant them out in late spring or early summer. Protect them during their first winter outside. The wood yields a yellow dye without a mordant to fix it. Plants For A Future records no known medicinal use.
