About
Phormium colensoi (syn. Phormium cookianum – see below), also called mountain flax, or wharariki in Māori, is a perennial plant that is endemic to New Zealand. The greenish, yellow or orange flowers are followed by twisted seed pods. It is less common than the other Phormium species, P. tenax or harakeke. Mountain flax is also known as whararipi, whatariki, mangaeka, kōrari tuauru (Williams 1971), wauraki (Bell 1890 sic.), coastal flax, hill flax and lesser New Zealand flax.
Uses
Wharariki is a taonga (sacred, treasure) species to Māori and numerous traditional cultivars have been used for various purposes. Refer to Ngā Tipu Whakaoranga [Māōri Plant Use Database] and the citations within and Te Kohinga Harakeke o Aotearoa – National New Zealand Flax Collection.
