Clumping bamboo would fit your bill.

If you had some sort of natural barrier, it would be great, but I have seen large plots full of running bamboo. You can just mow over the shoots, and that stops the shoots that you mow from growing, of course, there will be more shoots coming behind them. It will grow tall and dense fairly quickly. There are various colors, sizes and styles. There are also some that have different weather tolerances.
