The plant flag iris can anyone help?
Blue flag (Iris versicolor) is a native herb found in eastern and central Canada. This plant has been mentioned as causing poisoning in humans and animals, but case reports have not been found. The plant juice can cause dermatitis in sensitive individuals. Other iris species have also been implicated in poisoning of animals and in causing dermatitis in humans (see additional information under Iris pseudacorus). Because of the potential for poisoning, care should be taken to prevent access by livestock to blue flag, which grows in moist soils near rivers, lakes, and marshes (Fyles 1920, Cooper and Johnson 1984).
