|discussion=<p><i>Machaeranthera tanacetifolia</i> is present in the southern Rocky Mountains, western Great Plains, and southwestern desert regions. It has also been reported from Illinois and New York, but in both cases is most likely introduced. Because of its large showy heads, <i>M. tanacetifolia</i> is sometimes planted as an ornamental.</p>
