Awww. This is so sweet! I do think all the moisture might have caused this for your Rose Bush. My peach colored roses that got the measles had a rose disease. The garden center recommended removing the bush. I just haven’t had the courage to do that yet. I poured hydrogen peroxide around the bush and sprayed it too. It seemed to revive. I’m going to give it another chance next bloom cycle before taking it out.
Looks really cool and so pretty
