Hardy Shrubs That Thrive in New Zealand

Are you struggling to find hardy shrubs that can resist drought and require minimal upkeep in New Zealand’s unique climate? Whether you’re chasing a small shrub to line borders, or you’re after a taller screen, this article was created to help you find the perfect plant that won’t need babysitting.

These resilient plants not only withstand the challenges posed by varying weather conditions but also enhance garden aesthetics with minimal maintenance. By choosing hardy shrubs such as westringia, callistemon, nandina, viburnum, and azaleas, New Zealand gardeners can enjoy beautiful, sustainable landscapes all year round.

Westringia

Westringia, commonly known as Australian coastal rosemary, is perfect for New Zealand’s coastal areas (as well as inland gardens). This hardy shrub thrives in full sun to partial shade and is exceptionally drought-tolerant once established. Its grey-green foliage and soft, white or mauve flowers add a delicate touch to garden borders and function well as low-maintenance hedges. Westringia’s ability to withstand salt-laden winds makes it an excellent choice for coastal gardens, providing structure and beauty without demanding much care.

While most westringias are susceptible to root rot diseases when they experience wet feet, Mundi™ Westringia and Grey Box™ Westringia are able to withstand both periodic drought and flooding. Use them for depressed areas of the landscape, areas without proper drainage, and bioswales.

This shrub attracts pollinators such as native bees and birds, bringing life to any garden. Callistemon is well-suited to sunny spots and can endure dry conditions, making it a perfect candidate for water-wise gardens. There are varieties of all sizes which can be used as a screen, a low hedge, a striking specimen shrub, or even in containers for added colour on patios.

While many callistemons do struggle in wet conditions, all of the below varieties have shown remarkable resilience in periodic wet conditions with root rot diseases.
