Signs of Summer: Pink Rose Blooming

I don't know how this rose survives. It's been overrun by 2 shrubs for years now but somehow still manages to bloom. Takes it longer due to the lack of light so it just bloomed today. At least 3 more buds on it. If you look closely a the rose you can see the outer petals are wrinkly. I'm betting that is due to the heavy rain we had the last couple of days hammering the bud.
