Plant Biography

Phormium are a genus of only two species: Phormium tenax which is native to New Zealand and Norfolk Island, and Phormium cookianum which is native only to New Zealand.

Known as New Zealand Flax, these plants have historically been used by the Māori people as a source of fibre for creating textiles, rope and sails.

More recently they have become ornamentally popular around the world, becoming beloved for their spectacular form, leading to the creation of many new cultivars in recent years.
