I took this photo almost two weeks ago and only now are these same blooms starting to drop petals. They have been happily displaying their beauty on my deck for that long! This is a "Knockout Rose" that I purchased for less than $10 at Walmart a year ago. The plant stayed on the deck in the pot all winter, I pruned it way back in spring and it has been the most vigorous rose bush in my gardens. I struggle with my other, more expensive roses that need more attention. They grow more slowly and put out one or two or three flowers at a time. This bush is only a year old and going great guns. I suspect it is the hearty plant that is used as root stock for the hybrid roses. I'm enjoying it and it is effortlessly adding a lot of color and beauty to the view from my chair.
