Found throughout North America, the roots and tops have a delicious sweet vanilla-cinnamon flavor. Sweetflag grows in large colonies in wetlands and is fairly easy to cultivate in non-wetland conditions. We have a nice stand of these in one of our strawberry fields which is irrigated only in dry periods. Our seeds were collected from Wisconsin and Michigan which means it has less or none of the carcengenic properties that the other overseas selections have. But we would advise you not to use it for consumption due to other side effects the plant can have. Normally this species is used for its heavenly fragrance and the oil is extracted just for this purpose.
