The history of Phorium starts off in New Zealand. The plant itself had been used for centuries as medicine by the Maori people. The plant itself was brought to Britain during the 19th century around the time of major colonisation of New Zealand. The plant makes a large clump of leathery, strap-shaped leaves, with tall panicles of small, tubular flowers in summer. The plant itself is durable for the British climate at H5 and only needs sheltering in extreme winter conditions. The plant needs no maintenance and only dead leaves need to be pruned during the spring time. It is prone to potential pests and diseases so keep this in mind. The final height of the plant is between 2.5 m – 4 m (8.2 ft – 13.12 ft) and the final width is between 1.5 m – 2.5 m (4.9 ft – 8.2 ft)
