Iris versicolor, also commonly known as the Harlequin Blueflag, the Larger Blue Flag, and other variations of those names, is a species of Iris native to North America where it is common in sedge meadows, marshes, and along streambanks and shores. The species has been implicated in several poisoning cases of humans and animals who consumed the rhizomes, which have been found to contain a glycoside, iridin. The sap can cause dermatitis in susceptible individuals.
