Hi All!

Ever since visiting the Montreal Botanical Garden last fall, I've been searching for a source for the grass Pennisetum macrourum (African Feathergrass)...below is an image I took at the garden:

I finally found a seed source online, but after researching a bit more, it looks like it's only hardy to zone 9...and in those zones is considered a noxious weed...does anyone have any experience growing it?
