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.

Why Choose a Flax Border?

Flax borders stand out for their durability and versatility. Phormium species are evergreen perennials native to New Zealand, valued for their strong, sword-shaped leaves and resilience to wind, coastal exposure, and drought conditions. Their clumping growth habit makes them perfect for edging paths, marking boundaries, or mass planting for erosion control. A well-designed flax border also attracts native birds and supports biodiversity in your garden.

Top Flaxes for Stunning Borders

Selecting the right varieties is essential for a striking flax border. Consider mixing colours and heights for a dynamic, layered look. Popular choices include:

Planting and Caring for a Flax Border

Establishing a flax border is straightforward. Choose a sunny to partly shaded site with free-draining soil. Space plants according to their mature width, usually 60 to 90 centimetres apart for smaller varieties and up to 1.5 metres for larger species like Phormium tenax. Regular watering after planting helps them settle in, but once established, flaxes are highly drought-tolerant.

Apply mulch to suppress weeds and conserve moisture, and remove any damaged or old leaves in late winter to keep your border looking fresh. Flaxes rarely need feeding, but a general-purpose slow-release fertiliser in spring will promote healthy growth.

Creative Uses for Flax Borders

A flax border offers flexible design options:

Using mix-and-match varieties like Phormium 'Jester' and Phormium 'Velvet Underground' lets you create a unique flax border that brings structure and native beauty to your outdoor space year-round. Whether you have a coastal garden or a city courtyard, flaxes deliver impact and practical benefits without the fuss.
