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]
Description
[edit]This common weed can grow and produce flowers on plants that range from 4 inches (10 centimeters) to 36 inches (91 cm) tall. The rhizome is short and stout. The broadly elliptic leaves can be up to 5 inches (13 centimeters) long and taper with teeth towards the base.[7] Each flower head has 40-80 ray florets but no disc florets[8][9] Bracts surround the flower head; the receptacle (basal part of the flower on which the florets are attached) is flat and naked; heads tend to start together then become somewhat solitary on long leafless stems.[8] The stalks below the heads are covered with scattered, simple and gland-tipped black hairs and contain a milky substance.[9]
The pale yellow flowers are produced during all of the summer months. The fruit are dark brown achenes.[7]
