It's from Vintage Gardens Roses. I'd have posted the photo of Titian, too, but it came out really blurry. Ditto Hobby and Permanent Wave. I need to remember to use my real camera for close-ups of roses.
I was surprised by the size of the flower. I imagined that most ramblers had flowers that were one or two inches across, but this flower was certainly three, possibly four inches across. It also had a delightful tea smell, even as it lay desiccated on my desk two days after being plucked. Finally, for ID purposes, I noticed that the flower had several guard petals around the stamens: I didn't count, maybe it was four or five. There are only a few roses on which I have noticed guard petals. Bishop Darlington is the only other one that comes to mind.
