Hirschfeldia incana (short-pod mustard, summer mustard) is a biennial or short-lived perennial forb (family Brassicaceae) that is native to the Mediterranean. It is shorter in stature than black mustard (<40 dm) and highly branched, with soft-haired, pinnately-lobed leaves, yellow flowers, and short (<1.7 cm) seed pods that are appressed to stems. Short-pod mustard can suppress native vegetation through rapid growth and shading and flourishes in disturbed conditions and recently burned lands. It occurs on roadsides and other disturbed habitat, in shrublands, and in grasslands.
