Frozen Head State Park is famous for its stands of these pretty blue flowers. The cultivated Iris is Tennessee's State Flower. This small iris spreads by rhizomes on the surface of the ground. These rhizomes contain irisin, iridin, or irisine and are poisonous to swine and cattle. Humans are also poisoned by these plants if eaten.
