Iris tenax (Toughleaf Iris)

Floriferous and resilient, Iris tenax (Toughleaf Iris) is a slowly spreading rhizomatous evergreen perennial forming large, attractive clumps of tough, grass-like, light green leaves. In mid-spring to early summer, a profusion of purple to lavender-blue flowers, 3-5 in. wide (7-12 cm), often with yellow and white marking on the falls, appear just above the foliage. The flowers of this species show considerable variation in color as white, cream, and yellow variants also occur. They usually occur singly but sometimes in pairs. Very handsome and undemanding, Toughleaf Iris is great for rockeries, along the edge of gravel paths, or the front of the perennial border. It also enjoys meadow settings and can be used to edge woodland borders. Once established it will tolerate drought and gently reseed.
