Tall Teasel - Dipsacus - Invasive Species

Dipsacus is a genus of flowering plant in the family Caprifoliaceae. The members of this genus are known as teasel, teazel or teazle. Teasel is considered an invasive species in the United States. It is known to form a monoculture, capable of crowding out all native plant species, and therefore is discouraged or eliminated within restored open lands and other conservation areas. Teasels are easily identified with their prickly stem and leaves, and the inflorescence of purple, dark pink, lavender or white flowers that form a head on the end of the stems.
