Iris kaempferi, also known as Japanese Water Iris or Iris ensata, is celebrated for its extraordinarily large, flat-faced blooms that come in shades of purple, violet, pink, and white depending on the cultivar. One of the most spectacular flowering pond plants available, it blooms in early summer and produces flowers of exceptional size and beauty. Japanese Water Iris thrives in shallow water or boggy soil at the pond's edge, at a depth of up to 10cm, and grows best in a slightly acidic, humus-rich planting medium. A standout plant that rewards careful placement with a truly breathtaking display.
