    PHORMIUM

    Commonly known as New Zealand flax

    These architectural plants can be grown in tubs and make excellent features on the patio. They prefer a hot dry site and are perfectly hardy if sheltered from strong winds. In colder areas they need to be given some mulch or other protection around the base of the plant in winter.

    Genus of two species of evergreen perennials P. cookianum (Mountain flax) and P. tenax (New Zealand flax).

    They are found in scrub and swamps and on hillsides and riverbanks in areas ranging from coasts to mountains in New Zealand.

    The flax label originates from the Cook expedition where the native popuation wore garments similar to linens (made from flax).

    An industry was proposed for the Scillies in the late 1800s, probably for rope, but nothing came of it. Naturalised plants of P. tenax can be found all over the Isles.
