This shallow water-loving beauty boasts vibrant blue-purple flowers adorned with captivating veining, creating a stunning display - its sword-shaped leaves stand proudly, making it an ideal choice for pond edges or bog gardens.

Easy to thrive in damp soil or shallow waters, Iris versicolor is a less vigorous alternative to the yellow flag, and is perfect for various-sized ponds and lakes, as well as small water features or container gardening under the right conditions. With a penchant for moist to wet, humus-rich, acid soil and a preference for full sun, this iris is also attractive to wildlife.


  • Garden care:
    These plants are potted up (using a suitable aquatic compost) into aquatic pots. These pots are made of a fine mesh, which allows water to circulate through the compost, providing the plants with both oxygen and nutrients.

    If you are using them as a aquatic plant, they can be planted into neutral to acidic soil (for best results) up to a water covering of of 25cm (10in) deep. To enhance flowering divide congested clumps every three to five years.
