Iris versicolor, commonly known as blue flag iris 'Kermesina', is a clump-forming perennial with upright, sword-shaped green leaves forming dense, architectural foliage. In late spring to early summer it produces large, vivid flowers in deep crimson to reddish-purple shades with subtle yellow accents, creating a striking and colourful display along pond margins and in shallow water.
This cultivar is valued for its bold colour and contribution to wetland biodiversity, attracting pollinators and providing cover for pond-edge wildlife. Its upright, rhizomatous habit and tolerance of consistently moist or shallowly submerged soil make it ideal for pond edges, bog gardens, and naturalistic water features.
