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.[1][2] A perennial twining vine reaching 10 m (33 ft) long, it grows in thickets and forests at elevations from 100 to 1,700 m (300 to 5,600 ft), at least in China.[3][4] 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.[2][5] Local peoples occasionally consume its leaves and use it for erosion control.[4]
