Chinese Lespedeza

At first I did not know what it was. Then I decided to identify it: Lespedeza cuneata. The literature states that it forms dense stands that prevent anything else from growing. But I thought it was rather attractive and after all it was originally introduced as quail food so perhaps other birds feed upon it. Really, how bad could it get? Well three years later, it is thick and spreading and has formed a large dense stand. So I am spraying it with a solution of Roundup. I no longer see any beauty in this plant! Remove this plant as soon as you see it. The younger plants are rather easy to pull up, avoiding the use of any chemicals, but these are beyond pulling!
