Mikania vine (Mikania micrantha), also variously known as bitter vine, climbing hempvine, Chinese creeper, mile-a-minute weed, and American rope, is on the list of “100 of the World’s Worst Invasive Alien Species.” A perennial creeper native to subtropical regions of the Americas, it is a sun-loving plant that reproduces prolifically, grows at a rapid pace, and is very resilient. It wraps itself around other plants, blocking out the light that they need for photosynthesis so that they die.
