The Red Pine (Pinus resinosa) is a pine native to northeastern North America. The Red Pine grows in the area from Newfoundland west to southeast Manitoba, and south to northern Illinois and Pennsylvania, with a small outlying population in the Appalachian Mountains in West Virginia. In the Upper Midwest of the United States it is sometimes known by the confusing name Norway Pine[1] even though it is not native to Norway. It is the state tree of Minnesota.
