Rugosa Rose Hedge
I would like to put in a rugosa rose hedge that would grow no taller than 4 feet and be hardy down to zone 3. I want something that does not need winter protection and will provide nice hips for tea and the birds. I also need to keep them shorter, so I can keep an eye on my horses, since it will border the back yard, which overlooks their pasture.
Either one type of rugosa, or a mixture would be fine. I would also be open to other roses, if they were the right height and hardiness. I would appreciate all ideas and suggestions :)
