From Wikipedia, the free encyclopedia:

Dipsacus fullonum, syn. Dipsacus sylvestris, is a species of flowering plant known by the common names Fuller's teasel and wild teasel. 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 and often a noxious weed. The inflorescence is a cylindrical array of lavender flowers which dries to a cone of spine-tipped hard bracts. It may be 10 centimeters long. D. fullonum is the wild form of Fuller's teasel; the cultivated form is generally recognised as a distinct species under the name Dipsacus sativus.

Flowering Time: Blooms: June to August
