Phormium ‘Platt’s Black’ is a very popular dark-leaved variety of New Zealand Flax with vertical, sword-like, chocolate to black spiky leaves. Glossy on the surface, the foliage has a sheen on the back, providing a delightful architectural effect. Robust, this evergreen perennial is topped in summer with a dramatic flowering stalk bearing panicles of tubular, red flowers which attract nectar-seeking birds. Native to New Zealand, this Phormium is primarily grown for its attractive foliage and makes a stunning focal point in the garden, specifically when combined with and amongst brightly colored plants. Ideal for containers or massed in beds to create a dramatic textural effect! Adds architectural height to the garden and grows up to 3-4 ft. high and wide (90-120 cm). Hardy to USDA Zone 8a.
