Iris versicolor

Native Plants

Blue Flag

3 Photos


Summary

Moist and wet areas provide the perfect setting for blue flag (Iris versicolor) in the garden This iris grows 2-3’ tall and during late spring to early summer produces stems displaying several striking 3-4” wide blue flowers, each with a prominent yellow blotch. Its sword-like, upright foliage is an attractive accent to the summer garden. In addition to wet conditions, blue flag grows well in average soil and filtered shade to full sun. Blue flag makes an excellent focal point in a small pond or can be used in an area that is too wet for other garden plants. It combines nicely with royal fern (Osmunda regalis), turtlehead (Chelone glabra), cinnamon fern (Osmundastrum cinnamomeum), Virginia meadow-beauty (Rhexia virginica) and common boneset (Eupatorium perfoliatum). Zones 3-9.
