Looking for Pink Rose/Peony wallpaper found on Iphone 4 with IOS 5

I am trying to locate the beautiful pink flower wallpaper that came with my Iphone 4S. I think I might have had IOS 4 or 5 at the time. Its not in the default selections. It was a soft pink rose or peony that was looking to the left (sort of falling over) and there were raindrops somewhere on the screen. Please let me know where I can get this wallpaper. I have surfed the net and find nothing.
