The leaves are arranged around the stem in an alternating pattern.HabitatThe Western Wallflower has the greatest range distribution by elevation of any wildflower having been documented everywhere from 2,500 ft to 12,500 ft (800-4000m). Found in both the montane and alpine meadows of the Rocky Mountains and the desert canyons of the Great Basin and Colorado Plateau.Plant LoreIn Greek, Erysimum translates as “to help or save” in reference to the medicinal qualities of several species of these plants.
