Phormium cookianum

5 from 1 customers

Phormium cookianum, commonly known as Mountain Flax or Wharariki, is a graceful New Zealand native valued for its arching green leaves and tall flower spikes. It typically grows 1–1.5 metres tall and wide, making it ideal for borders, mass plantings, or coastal gardens. In summer, it produces yellow to orange tubular flowers that attract birds and pollinators. Hardy and tolerant of wind, salt, and poor soils, Wharariki thrives in full sun to part shade.
