Growing it

Propagation
cuttings, seed
When to plant
spring, autumn
Overwintering
In colder regions, move containers to a sheltered, frost-free location. If planted outdoors, provide a thick layer of mulch around the base to protect the roots from freezing temperatures.
In containers
It grows very well in containers, provided the pot is at least 30 cm in diameter and has excellent drainage.

Stem Cuttings

  1. Take a 10 cm cutting from healthy, non-flowering growth in late summer.
  2. Remove the lower leaves and dip the cut end in rooting hormone.
  3. Plant in a well-draining potting mix and keep in a warm, bright spot until rooted.

Group this plant with other salt-tolerant species to create a resilient coastal garden border.

  • New Zealand Flax · They share similar coastal environmental requirements and provide a nice contrast in leaf texture.
  • Hebe · These shrubs thrive in the same conditions and offer complementary flowering times.

Similar species

  • Coprosma robusta · A related species with a more upright growth habit and larger leaves.

Good to know

  • It is commonly known as the mirror plant because of its highly reflective, glossy leaves.
  • It thrives in salty, windy coastal air that would kill many other shrubs.
  • The genus name Coprosma comes from the Greek words for dung and smell, referring to the odor of some species when crushed.
