This is the best rose I have ever owned. It's tolerance to heat is amazing. In 110 degree weather the bloom is pristine day after day for a week. Then the yellow fades to white looking like a zebra. Most blooms last for 4 weeks some up to 6 weeks. I have found that the greater the temperature and full sun all day will give you greater contrast of colors to the point of being almost black. During the winter when the sun isnt intense the dark color will be medium red.
