Cirsium pitcheri
Also called Pitcher's Thistle, Dune Thistle, Sanddune Thistle
Cirsium pitcheri, sometimes called Pitcher's thistle or dune thistle, is a species of thistle native to sand dune shorelines along the upper Great Lakes. It is native to Indiana, Illinois, Michigan, Wisconsin, and Ontario. It is listed by the U.S. Fish and Wildlife Service as a threatened species.
The Pitcher's thistle is found exclusively along the shorelines of Lake Huron, Lake Michigan, and Lake Superior, particularly in areas of sand dunes. Two of the largest remaining populations have been identified in the Nordhouse Dunes area of the Manistee National Forest, and within Sleeping Bear Dunes National Lakeshore. In addition, Pitcher's thistle continues to grow and flower in some smaller state parks and private tracts along these lake shores.
