flax tree

The flax tree is a true icon of New Zealand gardens and landscapes. Renowned for its bold, architectural foliage and impressive versatility, the flax tree is an excellent choice for anyone wanting to add year-round texture, colour, and low-maintenance beauty to their outdoor space. Whether you’re seeking a strong structural plant for a modern garden, a hardy native for wetland restoration, or simply a striking focal point, the flax tree offers an abundance of benefits. With its sword-shaped leaves and tall flower spikes that attract native birds like the tūī and bellbird, the flax tree is as valuable for biodiversity as it is for design.

Phormium cookianum, commonly known as Mountain Flax or Wharariki, is a graceful New Zealand native valued for its arching green leaves and tall flower spikes. It typically grows 1–1.5 metres tall and wide, making it ideal for borders, mass plantings, or coastal gardens. In summer, it produces yellow to orange tubular flowers that attract birds and pollinators. Hardy and tolerant of wind, salt, and poor soils, Wharariki thrives in full sun to part shade.

Phormium tenax plant in a garden with green foliage.

Phormium tenax

5 from 1 customers

Phormium tenax, commonly known as the NZ flax or Harakeke, is a flax plant that produces erect, green, sword-like leaves. Stems rise above the foliage in summer to bear twisted-looking flowers that result in black seed pods in autumn, and the nectar produced by the flowers attracts both birds and butterflies. Harakeke grows as a clump to about 2 m tall and the same wide, performing best when planted in full sun on a well-drained site. It is a popular landscape option that is also often used to contrast with other plant colours. Mass planting on a bank not only provides an outstanding display but is also excellent for helping to stabilise the soil.

What is the Flax Tree?

Despite its common name, the flax tree is not a true tree but rather a large, clumping perennial native to New Zealand. Plants in the genus Phormium, such as Phormium tenax and Phormium cookianum, are commonly called flax trees. Grown for their dramatic foliage, which can range from deep green to vibrant shades of red, bronze, and gold, flax trees are highly resilient and thrive in a variety of conditions from coastal gardens to rural farms.

Uses for Flax Trees in the Garden

Flax trees can be used as specimen plants, in mass plantings, for shelter belts, or for attractive evergreen screening. Garden designers often choose cultivars like Phormium 'Taya' (Taya Flax) and Phormium 'Wildwood' (Wildwood Flax) for their stunning foliage colours and tidy forms. The robust root system of the flax tree makes it an ideal choice for stabilising banks and controlling erosion, especially in wet or exposed sites. Flax trees are also fantastic when used around ponds, streams, or as a backdrop in a native planting scheme.

Popular Flax Tree Varieties

Among the most popular is Phormium tenax, often called harakeke. This variety is a classic choice for both home gardens and restoration projects, growing into a large clump with upright, strong leaves. Phormium cookianum offers a softer, arching appearance perfect for mixed perennial borders. For gardeners seeking unique foliage, cultivars like Phormium 'Velvet Underground', Phormium 'Taya' (Taya Flax), and Phormium 'Wildwood' (Wildwood Flax) bring bold splashes of colour that really stand out.

Growing and Caring for Flax Trees

Flax trees are low-care and highly adaptable. They’ll tolerate full sun to part shade and thrive in most soil types, including those that are damp or coastal. While they are drought tolerant once established, regular watering helps them look their best through dry periods. Simply trim off old or damaged leaves at the base to keep your flax tree looking lush and tidy. Flax trees are virtually pest-free and rarely troubled by diseases, making them an easy choice for both new and experienced gardeners.

Bring structure and natural beauty to your garden with the New Zealand flax tree. Explore our selection including Phormium tenax, Phormium cookianum, Phormium 'Taya' (Taya Flax), Phormium 'Wildwood' (Wildwood Flax), and Phormium 'Velvet Underground' to discover the perfect variety for your landscape.
