Flower size can help distinguish different species: E. cheiranthoides has a flower size of about 0.2 to 0.3 inches. E. hieraciifolium (European Wallflower, Wormseed Mustard) is reported from only a few mostly southern counties in Wisconsin and not reported from any other midwestern states, has a flower size around 0.5 to 0.8 inches. E. capitatum (Sand-dune Wallflower) typically has orange colored flowers and is reported from only a few scattered counties in Wisconsin, has a flower size of about 1.2 to 2.2 inches. E. inconspicuum (Small-flowered Wallflower) has a flower size of 0.5 to 0.75 inches. E. asperum (Western Wallflower) is not reported present in Wisconsin, Michigan, Iowa, and Missouri, and reaches its most eastern distribution in Illinois, and has a flower size of about 0.75 inches. E. repandum (Bushy Wallflower) is not reported in Wisconsin, Minnesota, and the Dakotas, but present in the rest of the neighboring states, it has a flower size of about 0.5 to 0.6 inches. Differences in leaf shape can also aid in differentiating these species. Ethnobotany: The Chippewa used the roots to prepare a remedy for skin eruptions (Densmore, p. 350, 1928).
