Cogongrass (Imperata cylindrica) is considered to be one of world's most invasive weeds. As with many invasive exotic plants, it is native to Asia. However, it is a noxious weed throughout much of the world.
In southern states, cogongrass has taken over woodlands and pastures, has led to the loss of hunting lands, and is suspected to pose a danger to no-till agricultural lands. Most vegetation cannot compete with cogongrass, and it will grow just about anywhere except deep shade.
