Information about  Hirschfeldia incana from other sources

[Wikipedia] Native to the Mediterranean Basin: Hirschfeldia incana (formerly Brassica geniculata) is a species of flowering plant in the mustard family known by many common names, including shortpod mustard, buchanweed, hoary mustard[1] and Mediterranean mustard.[2] It is the only species in the monotypic genus Hirschfeldia, which is closely related to Brassica.[3] The species is native to the Mediterranean Basin but it can be found in many parts of the world as an introduced species and often a very abundant noxious weed.[4] This mustard is very similar in appearance to black mustard, but is generally shorter.[5] It forms a wide basal rosette of lobed leaves which lie flat on the ground, and it keeps its leaves while flowering.[6] Its stem and foliage have soft white hairs. Unlike black mustard, H. incana is a perennial plant.[5] Its leaves are edible and traditionally were used in some areas as a leaf vegetable.[7] (link added by Mary Ann Machi)
