I'm pretty new to the gardening scene and roses, so I need some expert opinions! I have this rose (pics below) growing in the tree line of my backyard. I did not plant it there--as far as I know it came up on its own. It is in full bloom right now (they started opening Easter Sunday), but it only blooms once each year. The blooms are small and start out medium pink and then fade to a lighter pink as the blooms age. I don't recall it having hips. The leaves are small. The vines are climbing up into the trees and are about 12-15' tall so far. I don't give it any care at all--no water, fertilizer, or sprays. It seems perfectly happy in the partially shady tree line. Any guesses on what this one is called?
