Northern Blue Flag/Blue Flag Iris

Iris versicolor

Iris versicolor, commonly known as the blue flag iris or northern blue flag, is a species of flowering plant native to North America. It belongs to the Iridaceae family, which includes other iris species.

Blue flag iris is a perennial herbaceous plant that typically grows in wetland habitats such as marshes, swamps, and along the edges of ponds and streams. It is known for its striking flowers, which bloom in late spring to early summer. The flowers are typically blue or violet-purple in color, though pink or white variations can also occur. Each flower consists of three upright petals (standards) and three drooping petals (falls) with yellow or white markings and a central yellow or white patch.

The foliage of blue flag iris consists of long, sword-shaped leaves that arise from the base of the plant and can reach heights of up to three feet. The leaves are green and may have a bluish tint.

Blue flag iris is cultivated as an ornamental plant in gardens and landscapes, particularly in wetland or bog gardens where it can thrive in moist, fertile soil. It is also valued for its ecological importance, providing habitat and food for various wildlife species such as bees, butterflies, and birds.

In addition to its ornamental value, blue flag iris has been used in traditional herbal medicine by Indigenous peoples of North America. However, it's important to note that the plant contains potentially toxic compounds and should not be ingested without proper preparation and guidance from a knowledgeable practitioner.
