Personally I think the best and most “Friendly Fence” is the Rose of Sharon. They come in all sorts of varieties too. You can usually find them in your local nurseries but you can also order them online or through flowering magazines. Just be sure if you order it online there is a 1 year guarantee…and be sure to keep that label and not to loose it. I guarantee that if you get 20 plants that 10 of them will not have made it and you can get replacements if this does happen!
