Iris setosa (Marginal Aquatic)

Iris setosa is perfect for adding a splash of vivid colour to damp borders, pond edges, or naturalistic planting schemes. The flowers have very large falls that are a vivid deep violet blue with delicate white markings, topped by discrete standards. The spring and early summer blooms are accompanied by mid-green, strappy, arching leaves that spread to form dense clumps. Thriving in ponds or boggy soils, it makes a reliable choice for wildlife friendly gardens, attracting pollinators while offering rich colour and graceful foliage.
