Salix myricoides
Salix myricoides, the bayberry willow or blue-leaf willow, is a species of flowering plant in the family Salicaceae, native to the Great Lakes region of the Midwestern United States, and to eastern Canada. It is typically found on beaches and dunes of the Lakes, and occasionally along inland streams and in fens, if calcareous. For example, in Maine it is found only on the ice-scoured shore of the St. John River. References
