Understanding the ideal climate and region for growing flax ensures these low-maintenance beauties will thrive in your garden for years to come.

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.
