Synonyms: In past was mistakenly called Dipsacus sylvestris Huds. in some references; binomial D. sylvestris Huds. has been used for wild teasel by majority of authors in N. America and the binomial D. fullonum L. reserved for the cultivated teasel- the opposite naming convention is used in Europe.

Common names: common teasel; wild teasel; card thistle

Dipsacus fullonum (common teasel) is a biennial forb/herb (family Dipsacaceae) sometimes used in flower arrangements, but was historically used as a hairbrush. It becomes a problem when it forms dense stands that are impenetrable to humans or livestock.
