Cirsium flodmanii, common names Prairie thistle, Flodman’s thistle, or (in French) chardon de Flodman, is a plant species native to Canada and to the north-central United States. It is known from every Canadian province from Québec to Alberta, as well as from the northern Great Plains and western Great Lakes regions of the US, plus Essex County in northeastern New York State.[2][3]
