Vincetoxicum rossicum (weed) (Kleopow) Barbar. - (pale swallow-wort)
The weed is native to eastern Europe and invasive in north-eastern North America. It suppresses native plants and can form dense stands in disturbed habitats, especially on calcareous soils. The vine-like plant grows to a length of 1.5 m and has oval, shiny leaves, up to 10 cm long, and tiny star-shaped flowers, about 5 mm in diameter.
The species is similar to Vincetoxicum nigrum, also invasive in North America, but the flowers are pink to maroon. It is also more shade tolerant compared to V. nigrum.
