A perfect plant for use in a rain garden or as a water plant , the copper iris takes its name from its unique reddish-copper color blooms which appear in May and June.Small plants, they typically reach about 2 feet in height. They love full sun, but will tolerate part shade if planted in consistently moist locations and will thrive in wet, clay soil. Copper iris attract hummingbirds and are pollinators for butterflies. They are also deer resistant. Because their habitats are disappearing, these native perennials are becoming much less common in nature. An easy plant to grow, copper iris aren’t usually bothered by insects or diseases.
