It is native to North America, where it can be found throughout the southeastern quadrant of the United States and in California and Baja California in the west. It grows in many types of habitat, including disturbed areas. It is an annual or biennial herb producing a basal rosette of leaves with comblike blades so deeply divided into many lobes that they may appear to have leaflets.

The fruit is a flattened, elongated silique up to 2.5 centimeters long containing tiny seeds.
