Climbing herbaceous vine up to 3 m tall with opposite, simple leaves that have distinct petioles. The leaves are triangular to
triangular-ovate in shape (3 to 15 cm long, 2 to 11 cm wide) with an attenuate apex and a cordate to hastate leaf base. The
inflorescence is a loose corymb and the flowers are borne in clusters of 4. The corolla is pinkish to purplish or sometimes white.
Growing in swampy woods, ditches, fence rows, pond margins, swamps. Sometimes forms dense mats that hinder regeneration of other
vegetation. Seeds are primarily wind-dispersed but can be moved unintentionally by people or animals. Whether wind-dispersed or by
animals, the pappus bristles are the main mechanism. They can act as a parachute or sail or can catch onto an animal via the same
feature or can be modified into a barb or awn. Vegetative reproduction is more important than sexual reproduction in this species
as broken stems can re-root and form new plants. The nodes root when in contact with the soil.
North and South America, from temperate to tropical regions. Invasive in many parts of the world, including Asia.
Used by the Seminoles to treat itchy skin. Also used for circumcision, wounds, and tumors. Planted as an ornamental, cover
crop, and for cattle feed.
