Adding late spring and early summer colour, as well as architectural interest to the edges of a pond or a reliably moist border, this gorgeous iris has been in demand for over 100 years. Its lilac-pink flowers are relatively small, but they form in clusters at the top of the stem, and once a decent sized clump has been established, you will have some to cut for the vase as well.


  • Garden care:
    Plant Japanese water iris (Iris ensata) in moist, fertile soil at the edge of a pond or in a boggy area, with the rhizomes just at or slightly below the soil surface. Space plants about 45-60cm (18-24in) apart to allow room for growth, water well after planting, and keep the soil consistently moist during the growing season.

    Apply a balanced fertiliser in spring and remove old foliage in late winter to encourage healthy new growth and abundant flowering.
    • Humans/Pets: Harmful if eaten
