Dipsacus fullonum* /Teasel Family
(INN) Rank 2
It could be easy to confuse this plant with a thistle, it has hundreds of tiny pinkish-purple flowers and the leaves and stems are very prickly. It is a member of the Teasel family, Thistles are in the Composite family. Teasel is a European import, it can grow in very thick patches along the interstates and other highways. The prickly dried seed heads were once used to "tease" wool. These were found when I stopped at a convenience store with my sisters-in-law in Kingsport; I never pass up a chance to take a picture.
