We know exactly what you mean

The deeprooted sedge (Cyperus entrerianus) is about to make its South Carolina debut, according to this article from MyrtleBeachOnline.com. The species, native to South America, has been spreading northward since it entered the U.S. around 1990. It's considered a serious threat in agricultural areas, where the seeds spread by sticking to pretty much anything that moves, or by passing through the digestive systems of grazing animals and wildlife that have apparently taken a liking to the plant. (Bonus points to The Sun News for using the sedge's scientific name.)
