Peppermint was introduced to the U.S. by English settlers, with cultivation beginning in Massachusetts in the early 1800s, before larger scale production commenced in New York State (1830s) and then the Midwestern states (mid 1800s) (1). Because of favorable growing conditions and the effects of Verticillium wilt, a fungal disease, the early 1900s saw a migration of peppermint cultivation to the Northwestern states (Oregon, Washington, and later Idaho). As of 2014, the Pacific Northwest (Idaho, Oregon and Washington) accounts for 84 % of the U.S.
