Native to the Americas, mikania vine is a multi-stemmed perennial creeper and climber. It rapidly chokes and smothers areas it has colonised.
Mikania vine is a serious weed in West Africa, India, South-East Asia, Indonesia and the Pacific Islands. In Australia, it has been found in north Queensland. Suitable growing conditions for mikania also exist in eastern Queensland, north-eastern New South Wales, northern Western Australia, and coastal regions of the Northern Territory.
