Iris versicolor (“Blue flag Poison flag”) marginal pond plant

Iris versicolor, also called Blue Flag or Poison Flag, is a striking UK-grown marginal pond plant with vibrant flowers.
Firstly, it produces beautiful blue to violet flowers with intricate markings, blooming from late spring to early summer.
Moreover, it adds height and bold colour to pond edges, bog gardens, and damp borders.
Because it’s UK-grown, this native species is well-adapted to local climate and soil conditions, ensuring reliable growth.
In addition, Iris versicolor thrives in moist to wet soil and prefers full sun to partial shade for best flowering.
Also, it supports local wildlife by attracting pollinators such as bees and butterflies.
Although it is called Poison Flag, it is safe to grow in garden ponds with proper handling.
To maintain its health, water regularly during dry periods and divide clumps every few years.
Furthermore, cut back dead foliage in autumn to keep a neat garden appearance.
Equally important, its tall, sword-shaped leaves provide year-round structure and texture to water gardens.
Notably, it tolerates occasional flooding and wet soils, perfect for pond margins.
Unlike many aquatic plants, it spreads slowly, making it manageable in garden settings.
Order your UK-grown Iris versicolor today and enhance your pond with bold colour and natural beauty!

After foliage has died back in Autumn cut back to just above the water surface.

If trimming left until spring take care not to damage emerging shoots.
