Zuzu, it's hard for me to imagine your garden lacking any rose, but I'll take your word for it, as I know your record-keeping is excellent. If I had as many roses as you maintain, I'd have to use a barcoding machine to keep up with them. I get frustrated when I can't remember a few names of the hundred or so varieties I tend, but I can't imagine remembering 1,500 names, nor the details of each one's habits.
Thanks for creating the "canvas" for our rose portraits here!
