Climbing, spreading, purple roses?
Although I don't consider myself a rose aficionado, roses grow like crazy on my property with basically no effort from humans. So, with that in mind, I'm wondering if I can find a rose, or roses, that I can use to fill in a section of fence that's about 20 feet long and 4 feet high. I'd like purple flowers--the darker, the better--and something that would really grow and spread and eventually obscure the fence. Is there such a creature? :) Oh, assuming I need multiple plants for this large an area, alternating white and purple would be an option, so consider white, too.
