I love pampas grass. I think it is so pretty because it is so simple. It goes well with just about everything. It's a great way to edge something that you just don't want to have to fuss with very much.
You do have to watch where you transplant it because pampas grass grows so fast, it can overtake your flower beds! They grow unlike regular grass does. It doesn't need much water to thrive.
Another thing to be aware of, it is so dense that often rats and mice like to make it their homes.
Oh and something I am sure you have already discovered, the leaves are extremely sharp. So avoid planting it where anyone walks by it a lot such as walkways because it does cut the skin.
