A food plant for many insects. Sometimes cultivated for cut flowers, and longlasting in a vase! A tea made from the leaves was used as a laxative and to treat skin diseases. Has diuretic and fever-reducing properties. This plant was common in an area where I played as a kid and I remember how you could open its little dragon jaws. A species of toadflax native to Europe and Asia, and now common in North America.
