Isatis tinctoria, with Woad (
/ˈwoʊd/; or glastum) as the common name, is a flowering plant in the family Brassicaceae. It is commonly called dyer's woad, and sometimes incorrectly listed as Isatis indigotica (a newer and invalid name for the same plant). It is occasionally known as Asp of Jerusalem. Woad is also the name of a blue dyestuff produced from the leaves of the plant.
