The most commonly seen New Zealand Flax in our climate and arguably one of the most hardy to cold. Deep maroon/purple evergreen foliage in a large clump to 5′ x 5′ ultimately in a hot position and full sun in rich, well drained soil. Regular summer water increases the growth rate which in turn establishes the plant more thoroughly. The more established the Flax the more vigorously it returns if it gets hit by cold. If it does, try not to cut the whole thing to the ground but leave as many viable leaves as possible for food to aid in the recovery. Great plant for hot hellstrips and containers. Borders. etc. Following mild winters (above 20ºF) it may send up 6′ spikes with duckbill shaped yellow flowers in summer. Thrives at the Oregon Coast where it seldom is ever bothered by cold and where it absorbs blasting salt laden winds happily. High deer resistance.
