Comparing a few dark purple-y pink/red roses that hold their color well, even with lots of heat and sun. In all the photos the aging blooms are toward the back. Younger ones are toward the front, so you can see the amount of fading. It has been very hot here unfortunately, already over 100 for a few days recently.
