Selected images for dog-strangling vine, European swallowwort (Cynanchum rossicum )
European swallowwort is an herbaceous, twinning, long-lived perennial vine. Leaves are opposite, dark green, oval, shiny, 3-4 in. (7.6-10.2 cm) long and 2-3 in. (5.1-7.6 cm) wide. Flowering occurs in June to July, when pink to reddish, 5-petaled, star-shaped flowers appear in clusters. Flowers are approximately 0.25 in. (0.6 cm) across and are covered with white hairs. Fruit are pods, similar to milkweed pods, which are slender, 2-3 in. (5.1-7.6 cm) long and split to reveal small seeds with tufts of white hair. The hair allows the seeds to be readily dispersed. European swallowwort invades upland areas with a wide range of light and moisture conditions. European swallowwort is native to Europe and was likely introduced into the United States for ornamental purposes.
