Dipsacus fullonum, syn. Dipsacus sylvestris, is a species of flowering plant known by the common names wild teasel or fuller's teasel, although the latter name is usually applied to the cultivated variety D. fullonum var. sativus.[2] It is native to Eurasia and North Africa, but it is known in the Americas, southern Africa, Australia and New Zealand as an introduced species.
It is a herbaceous biennial plant (rarely a short-lived perennial plant) growing to 1–2.5 metres (3.3–8.2 ft) tall. The inflorescence is a cylindrical array of lavender flowers which dries to a cone of spine-tipped hard bracts. It may be 10 centimetres (3.9 in) long. The dried inflorescence of a cultivar was historically used in textile manufacturing as a tool for fulling.
