Hedgemustard (Sisymbrium officinale)
Description
Sisymbrium officinale, known as hedge mustard, (formerly Erysimum officinale) is a plant in the family Brassicaceae. It is found on roadsides and wasteland, and as a weed of arable land. A native of Europe and North Africa, it is now well-established throughout the world.It is distinct from the mustard plants which belong to the genus Brassica. S. officinale is similar to other Sisymbrium, but differs in its tall, erect stems with tiny flowers and fruits that are compacted parallel to the stem instead of hanging free.Hedge-mustard is food for the caterpillars of some Lepidoptera, such as the small white (Pieris rapae).
