Phormium tenax (New Zealand Flax)
Stunning focal point for the garden, Phormium tenax (New Zealand Flax) is a very ornamental and robust evergreen perennial featuring a basal rosette of rigid, sword-shaped, upright leaves up to 10 ft. long (3 m), ranging from green to bronze to chocolate-brown. Some cultivars produce variegated leaves, beautifully striped or edged with pink, red, orange or purple, adding a bright note to the garden year-round. The architectural foliage is topped in summer with a dramatic flowering stalk reaching up to 12 ft. (360 cm) and bearing panicles of tubular flowers, about 2 in. long (5 cm), in shades of deep red or reddish-orange. Showy, they attract nectar-seeking birds.
