Blue Flag Iris - Iris versicolor

The Blue Flag Iris is native to North America, in the Eastern United States and Eastern Canada. 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.

Other names include: harlequin blueflag, larger blue flag, northern blue flag and poison flag.
