Phormium tenax (harakeke in Māori, New Zealand flax) is an evergreen perennial plant from New Zealand and Norfolk Island. It is an important fibre plant and also a popular garden plant.[1]

The plant grows as a clump of long, straplike leaves up to two meters long. It grows a much taller flowering shoot, with dramatic yellow or red flowers.[1]

The fibre from the plant was used by the Māori of New Zealand to make baskets. It was also used in rope and sail making.[2] after the arrival of Europeans up until at least WWII

In other countries Phormium tenax is an invasive species. On Saint Helena it is taking over the land from the critically endangered species Elaphoglossum dimorphum.[3]

Ecology[change | change source]

The jumping spider Trite planiceps lives in the rolled-up leaves of this species. Phormium tenax grows on the coast where it is important in the breeding habitat for the endangered Yellow-eyed Penguin.[4]
