Where It Grows

New Zealand*,

Cultivation

Plants can be grown by cuttings.

Propagation

Seed is best sown as soon as it is ripe in a greenhouse or cold frame. Stored seed can be sown in spring in a cold frame. Germination is often slow, taking more than 12 months even with fresh seed. Prick seedlings out into individual pots once large enough to handle, and grow on under glass for at least their first winter before planting out in late spring or early summer. Provide some cold protection during the first winter outdoors. Cuttings of mature wood from the current year's growth can be taken in autumn and rooted in a frame.

Other Uses

A yellow dye obtained from the wood does not require a mordant. The plant makes an excellent medium-height ground cover.

Notes

There are about 90 Coprosma species.
