Carduus is a genus of flowering plants in the family Asteraceae, and the tribe Cardueae, one of two genera considered to be true thistles, the other being Cirsium.[2] Plants of the genus are known commonly as plumeless thistles.[3][4] They are native to temperate Eurasia and North Africa,[1] and several are known elsewhere as introduced species.[4] This genus is noted for its disproportionately high number of noxious weeds compared to other flowering plant genera.[5]
