About Hirschfeldia incana (L.) Lagr.-Foss.
Hirschfeldia incana (formerly known as Brassica geniculata) is a flowering plant species belonging to the mustard family. It has multiple common names: shortpod mustard, buchanweed, hoary mustard, and Mediterranean mustard. This is the only species in the monotypic genus Hirschfeldia, a group that is closely related to the genus Brassica. The species is native to the Mediterranean Basin, but it has been introduced to many other regions around the world, where it often grows as an abundant, noxious weed. This mustard closely resembles black mustard in appearance, but it is typically shorter in overall height. It grows a wide basal rosette of lobed leaves that lie flat against the ground, and retains its leaves throughout its flowering period. Soft white hairs cover its stem and foliage. Unlike black mustard, H. incana is a perennial plant. Its leaves are edible, and have been traditionally used as a leaf vegetable in some areas.
