Carduus crispus

Carduus crispus has upright growth,[3] and individuals can grow up to 3 metres (10 ft) tall, with the typical height being 50–180 centimetres (19+1⁄2–71 in).[10] The round-shaped fruit is flattened, and attached to one end are long unbranched hairs[10] that aid wind dispersal.[14] C. crispus is naturalized in Greenland, parts of the United States and Canada, and India[15][14] It needs a lot of sunlight, and therefore is not shade tolerant.[5] This species can also be called a noxious weed in North America, and can be found in areas such as pastures and along the sides of the road.Carduus crispus is an introduced species in North America, and a noxious weed in several U.S. states, including West Virginia.
