|discussion=<p><i>Cirsium flodmanii</i> ranges from Saskatchewan and Alberta south through the northern Great Plains and intermountain valleys of Montana and Wyoming to northeastern Colorado and east through the prairies to Minnesota and Iowa, and in widely scattered locations eastward to northern Illinois, southern Wisconsin, southern Ontario, and southern Quebec. It is known to hybridize with <i>C. muticum</i> and <i>C. undulatum</i>. Hybrids between <i>C. flodmanii</i> and <i>C. undulatum</i> are highly sterile with numerous meiotic irregularities (S. Dabydeen 1987).</p>
