Mikania cordata

Mikania cordata, the African mile-a-minute or heartleaf hempvine, is a species of flowering plant in the family Asteraceae, disjunctly distributed across the Old World Tropics. A perennial twining vine reaching 10 m long, it grows in thickets and forests at elevations from 100 to 1700 m, at least in China. It is a rapidly-growing climber that suppresses the growth of other plants (including kudzu) and is considered a more dangerous noxious weed than Mikania micrantha. Local peoples occasionally consume its leaves and use it for erosion control.
