Hi Debra. My favorite yellow grafted Hybrid Tea rose is Midas Touch. It is disease resistant (no blackspot) and survives zone 7 winters. It takes the heat and high humidity here in the summertime with no adverse effects. This healthy rose is fragrant and is a bright cheerful yellow - it may knock your socks off! It does not fade in color quickly and when it does, it's still a nice pleasing yellow tone. I am including 2 photos. Best of luck to you in your quest. - Margie, Long Island
