The Yellow Flag Iris, scientifically known as *Iris pseudacorus*, is a perennial plant native to wetlands in Europe, Asia, and North America. It features striking yellow flowers that bloom in late spring to early summer, growing up to 3 feet tall. The plant thrives in moist soil and can often be found along riverbanks, ponds, and marshes. This iris species is known for its sword-like leaves, which can reach lengths of 2 feet. While it adds beauty to gardens and natural landscapes, the Yellow Flag Iris can become invasive in some regions, outcompeting native plants and disrupting local ecosystems.
