Reynoutria japonica, better known as Fallopia japonica, the current botanical name not yet in use, is considered a dreaded invasive plant outside its native East Asia. In suitable locations, of which there are many, Japanese Knotweed is adaptable, spreading over large areas and leaving no room for other plants.
