Leaves: Leaves mostly clustered in a basal rosette and on the lower part of the stem, alternate (1 per node), elongated, deeply lobed or toothed.

The whole plant has a distinctly unpleasant odour, somewhat resembling that of rotting turnips. Flowers from May to September.

Habitat: Stinking wall-rocket usually occurs in coarse soils along roads, railways, beaches, around buildings and in waste places in southern Ontario

Similar Species: It is distinguished by its leaves being mostly clustered near the base, the upper part of its stem being usually more or less branched and spreading, its lemon yellow flowers followed by short seedpods, and the very unpleasant odour from all parts of the plant.
