Erysimum, or wallflower, is a genus of flowering plants in the cabbage family. It includes about 180 species of popular garden plants and many wild forms. The genus Cheiranthus is sometimes included here in whole or in part. Erysimum has since the early 21st century been ascribed to a monogeneric cruciferous tribe, Erysimeae, characterised by sessile, stellate and/or malpighiaceous trichomes, yellow to orange flowers and multiseeded siliques.
