I’m sorry I couldn’t get a better picture, this is the only one I have. But its a floofy tall plant and at the bottom f these floofs isgiant grass, do you know what this is called.
I cannot be 100 % certain on this one, because I cannot see the lower portion of the plant. However, it is most likely pampas grass, Cortaderia selloana, a commonly cultivated mound-forming grass. Similar grasses include Arundo donax and several species of Miscanthus.
You can find out more about it here: http://en.wikipedia.org/wiki/Cortaderia_selloana
I hope this helps!
