Discover the enchanting beauty of Iris versicolor, commonly known as Northern Blue Flag, a stunning herbaceous perennial from the Iridaceae family, native to the wetlands of Northeastern North America. This clump-forming iris captivates with its narrow, sword-like blue-green leaves and showy bluish-purple flowers, each detailed with bold purple veining and a striking yellow blotch. Reaching a height of 24-36 inches, it's ideal for water gardens, pond margins, and moist borders, flourishing in full sun to part shade and in conditions ranging from medium moisture to up to 4 inches of standing water. Northern Blue Flag blooms from May to July, attracting butterflies and hummingbirds, adding vivid color and life to your garden. It's resilient against deer and naturally forms colonies, offering a low-maintenance solution for creating vibrant naturalized landscapes. However, caution is advised as its rhizomes are toxic. A symbol of diversity and grace, this iris is named after the Greek goddess of the rainbow, perfectly mirroring its varied hues.
