Valeriana edulis, commonly known as edible valerian or tobacco root, is a species of flowering plant native to North America in the family Caprifoliaceae. Three subspecies with geographically disjunct distributions are recognized: V. e. edulis occurs in the North American Cordillera from southern British Columbia to northern Mexico and from central Oregon to the Black Hills. V. e. ciliata occurs in from the Driftless Area around the southern Great Lakes into the Ontario Peninsula. V. e. procera occurs in the North American Cordillera of central Mexico.
