Mark - You have to realize that I sit at over 6000ft, so, at my altitude, the sun's more intense. For every 1000ft, the sun is 6% more intense, so, at 6000+, I'm around 36% more intense with UV than at sea level. So, on a hot day like today, most of my roses will last from morning to night.. then it's chop chop because they look HORRIBLE. Totally fried.
