Information about Dipsacus fullonum
[Cal-IPC] Ecological impact: 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. (link added by Mary Ann Machi )
