Description

Coprosma robusta, commonly known as karamu, is a versatile and significant native shrub in New Zealand's natural landscapes. This evergreen plant is integral to various landscaping and ecological projects due to its adaptability, rapid growth, and ecological benefits. Thriving in lowland and lower montane areas, karamu is commonly found throughout the coastal regions of both the North and South Islands.

 Coprosma robusta is distinguished by its glossy green leaves and the masses of bright orange berries it produces from January to July. These berries are a major attraction for native birds like bellbirds and tui, making karamu an excellent choice for bird-friendly gardens and enhancing local biodiversity.

Karamu is well-suited to a range of environments, thriving in both full sun and partial shade. It can adapt to various soil types but prefers well-drained soils and can withstand periods of drought. This resilience makes it a popular choice for different landscaping purposes, including as a fast-growing shelter, hedging, and nurse plant.

One of the most remarkable aspects of Coprosma robusta is its role in restoration projects and revegetation efforts. As a nurse plant, karamu helps stabilize soil and provides essential shelter for other native species, making it a crucial component in the rehabilitation of degraded environments. Its ability to compete effectively with invasive species like gorse further enhances its value in shrublands and revegetation initiatives.
