Flax in New Zealand

New Zealand flax describes the common New Zealand perennial plants Phormium tenax and Phormium colensoi, known by the Māori names harakeke and wharariki respectively. Although given the common name 'flax' they are quite distinct from the Northern Hemisphere plant known as flax (Linum usitatissimum).

P. tenax occurs naturally in New Zealand and Norfolk Island, while P. colensoi is endemic to New Zealand. They have played an important part in the cultural and economic history of New Zealand for both the Māori people and the later European settlers.

Both species and their cultivars have now been widely distributed to temperate regions of the world as ornamental garden plants – and to lesser extent for fibre production.^[1][2]
