Corokia cotoneaster

Corokia cotoneaster, commonly known as the wire netting bush, is a unique, slow-growing evergreen shrub belonging to the Argophyllaceae family. It is widely recognized for its tangled, zigzagging stems that create a sculptural, minimalist appearance, making it a highly desirable plant for modern and formal garden designs.

Originating from New Zealand, this plant has adapted to withstand windy and exposed coastal environments. In its native habitat, it grows on rocky outcrops and cliffs, which explains its tolerance to poor soils and its preference for excellent drainage. It is commonly cultivated in temperate climates where it can thrive outdoors year-round.

Botanically, the plant features small, stiff leaves that appear deep green on top and greyish-silver underneath. It produces small, star-shaped yellow flowers in spring, followed by bright red or yellow berries in autumn. The dense, interwoven structure of its branches allows it to be used as a natural, low-maintenance screen or a topiary subject.

For optimal growth, Corokia requires a sunny or semi-shaded location and a well-draining soil mix. It is drought-tolerant once established but performs best when given consistent, light irrigation. Because of its hardy nature, it is relatively low-maintenance, requiring minimal fertilization and focusing mainly on structure maintenance.

Key cultivation and care recommendations include:

• Pruning annually to maintain the desired shape and density.
• Providing a sandy, well-draining substrate to prevent root rot.
• Monitoring for pests such as aphids or spider mites, especially in glasshouse conditions.
• Providing winter protection in areas prone to hard, prolonged frosts.
