Also called Black Swallow Wort, Black Swallowwort, Dog Strangling Vine, Black Dog Strangling Vine, Louise's Swallow Wort, Louise's Swallowwort
Dark vincetoxicum is a perennial, twining herbaceous vine from southern Europe that is invasive in parts of North America. It is grown mainly as a wild or ornamental-curiosity plant, and its key trait is its vigorous, self-seeding spread.
Vincetoxicum nigrum, a species in the family Apocynaceae, also known as black swallow-wort, Louise's swallow-wort, or black dog-strangling vine, is a species of plant that is native to Europe and is found primarily in Italy, France, Portugal, and Spain.
