Zuzu, I think I have that rose -- a floribunda hybridized by Bill Warriner back in the '80's -- SUMMER FASHION. I love it because it's basically a photosensitive ivory flower whose petals turn more soft coral colored as the bloom ages. I don't have any pictures, but by next spring I'll try to get some -- and it looks just like your flower. It's a beautiful floribunda!
