What is the Mountain Flax Flower?

Mountain flax flower belongs to Phormium cookianum, a New Zealand native commonly called mountain flax or wharariki. The flax’s flower spikes are a sight to behold, with clusters of tubular, yellow-green to red-toned blooms that appear in late spring to early summer. These nectar-rich flowers are a favourite for tūī, bellbirds, and other pollinators. The arching shape of the mountain flax flower’s stem gives the plant a soft, flowing look that beautifully complements modern and traditional landscapes alike.

Growing Mountain Flax Flower in Your Garden

Mountain flax is prized not only for its striking flower spikes but also for its adaptability. It thrives in full sun to part shade and tolerates a range of soils, from coastal sand to damp stream banks. Perfect for both large gardens and compact spaces, the mountain flax flower provides a dramatic focal point or can be mass-planted for erosion control on slopes. Once established, mountain flax handles wind, frost, and even coastal conditions, making it one of the most versatile natives for New Zealand gardens.
