Very, very tall hardy grass--what is it?
In on the top of a windy hill outside Romney WV in a very exposed site next to a Burger King restaurant is a very tall grass that has been growing there for many years. The tan colored (in late fall and winter)plumes must be just about 14 feet tall (a careful estimate). I have heard that Pampas grass is hardy to only Z7, but this is 6A, and a harsh 6A at that. I have seen "hardy" Pampas grass advertized. Could this be a kind of hardy Pampas grass or something else? If something else, what could it be? I think this is a gorgeous plant and want one or two.
