Diplotaxis muralis is a species of flowering plant in the Brassicaceae family. It is native to Europe, Asia, and Africa, and has spread to temperate regions globally. The plant is characterized by its erect, mustard-like growth, rarely reaching half a meter in height. Its leaves are lobed, and the stems bear dense clusters of yellow or occasionally light purple flowers with small oval petals and prominent anthers. The fruit is a pod-like silique measuring two to four centimeters in length. It was first described in 1821 and is found in regions including Canada, the United States, and parts of Europe, as well as in South Africa, Chile, and Ireland.
