Facts About

Mountain ironwort is native in the region from southwestern Europe to Pakistan, including northern Africa. It rarely turns up in North America, having been collected only in South Dakota, Arkansas and Connecticut. The corolla can be yellow or red-brown to black with yellow on the lower lip.
