Phormium tenax New Zealand flax Evergreen perennial (1 Page of 5) The Phormium tenax plant species is found in New Zealand. Naturalized in Britain in S.W. England[17]. It is a member of the Agavaceae family. Common gardeners may know the plant as New Zealand flax. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Phormium tenax Common Name: New Zealand flax Family: Agavaceae Author: Forst.&Forst.f. Known Hazards: None known Mature Height: 3 Mature Width: 2 Habitat: Lowland swamps and intermittantly flooded land, North South Stewart, Chatham and Aukland Islands[44].
Cultivation Notes: Prefers a rich loamy soil[1] but is not too fussy, succeeding in peaty soils and in boggy moorland[11]. Tolerates light shade[1] but prefers full sun[200]. Plants can be grown in quite coarse grass, which can be cut annually in the autumn[233]. Prefers a sheltered position[42] but tolerates maritime exposure[75]. Plants tolerate occasional flooding with saline water[200].
Plants can withstand temperatures down to about -11°c[42], but they can be killed in very severe winters in Britain[11].
A polymorphic species[78], there are many named varieties grown in Britain[11, 200]. This species hybridizes readily with P. colensoi and there are many named forms that may be hybrids with that species[11].
This plant has been considered for commercial cultivation for its fibre, though there is some difficulty in mechanically extracting the fibres due to the presence of a gum in the leaves. An alkali has been successfully used to break down the gum but this weakens the fibre. The Maoris had selected many different cultivars for different uses[153].
Members of this genus are rarely if ever troubled by browsing deer or rabbits[233].
