|discussion=<p>Subspecies trachysperma is found mainly in the Great Plains and western states. Populations in the eastern United States are presumably adventive, as are those in eastern Ontario, where it has been found spreading in disturbed areas, such as quarries and roadsides (B. McBride 2006).</p>
