Iris louisiana, commonly known as Louisiana iris 'Colorific', is a clump-forming perennial with tall, upright, sword-shaped green leaves that give strong vertical structure. In late spring to early summer it produces large, showy flowers blending rich purple and violet tones with lighter highlights and subtle yellow markings, creating a vivid and eye-catching display.
This cultivar is valued for its bold colour contrast and its contribution to wildlife-friendly wetland planting. Its vigorous, upright habit and preference for consistently moist soil make it well suited to pond margins, bog gardens, and shallow water, where it provides both architectural form and seasonal interest.
