Phormium tenax plant in a garden with green foliage.

Phormium tenax

5 from 2 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 Green Flax?

Green flax refers to New Zealand’s iconic native species, most notably Phormium tenax. This hardy plant features robust green leaves and striking flower spikes that attract native birds and pollinators. Green flax thrives in a variety of soils, tolerates coastal winds, and copes well with both wet and dry sites, making it an ideal option for almost any garden setting. In addition to Phormium tenax, there are compact green flax cultivars perfect for smaller spaces or pots, such as Phormium 'Pepe' (Dwarf Flax) and Phormium 'Green Dwarf'.

How to Use Green Flax in Your Garden

Green flax excels as an architectural feature or mass planting along borders and driveways. Its strong vertical form provides year-round interest and acts as an excellent backdrop for other native shrubs or flowering perennials. Plant green flax near water features for a lush, natural effect or mix it with colourful cultivars like Phormium 'Spearmint' (Spearmint Flax) and Phormium 'Moonraker' (Moonraker Flax) for a layered, eye-catching display. Green flax is also well suited for ecological restoration projects, as its dense root system stabilises soil and prevents erosion on banks and slopes.

Green Flax Care and Maintenance

Caring for green flax couldn’t be easier. Once established, these tough plants need little attention—simply remove any dead or damaged leaves to keep them tidy. Green flax is drought tolerant and copes well with coastal conditions, though it also flourishes in damp areas. For best results, plant green flax in well-drained soils and add mulch to conserve moisture. Mature specimens can reach substantial heights, especially Phormium tenax, so give them ample space to grow. Compact varieties like Phormium 'Green Dwarf' are perfect if you want all the impact of green flax in a smaller form.

Discover More Flax Varieties

If you’re exploring options beyond traditional green flax, browse high-performing cultivars such as Phormium 'Spearmint' (Spearmint Flax) with its minty-green striped foliage, or the petite Phormium 'Pepe' (Dwarf Flax) ideal for rockeries and pots. For a unique twist, Phormium 'Moonraker' (Moonraker Flax) offers creamy margins and compact growth.

Green flax remains a timeless choice for gardeners seeking structure, resilience, and native beauty. Whether mass planted, in mixed borders, or featured as a stand-alone specimen, green flax is sure to impress for generations to come.
