|discussion=<p><i>Packera cana</i> is found in a wide variety of habitats and in a wide range of elevations throughout the western Cordillera and into the High Plains. Morphology is relatively uniform throughout its range except that alpine specimens are notably dwarfed and are often mistaken for <i>P. werneriifolia</i>, which differs by its consistently scapiform habit.</p>
