Hieracium lachenalii, also known as common hawkweed or yellow hawkweed, is a species of plant in the tribe Cichorieae within the family Asteraceae. It is native to Europe but has become established as a weed in Australia and parts of North America. The species was widely known for many years as H. vulgatum,^[3] but more recent studies have indicated that the two names represent the same species. The name H. lachenalii was coined in 1802,^[4] H. vulgatum in 1819,^[5] so the older name is to be used.^[6]
