That had occurred to me too, but checking the height for Appleblossom Flowercarpet, it seemed to me to be possible if it's taken into account that roses tend to be a lot bigger here than it says on the tin. I was also considering the fact I've seen in my own neighbourhood here many really huge specimens of Flower Carpet Pink [whose height is listed as about the same as Appleblossom's] that, if they were to concentrate on high jump rather than broad, would clear Box Hill Hedge's fence in a trice- by hurdling, nevermind the Fosbury Flop. Everything about the two seems identical, unromantic as it seems; I really hoped this might be some long lost thing from the early 20th century. Just let me get a glimpse of Appleblossom's hips, just in case, then I'll give up this line of enquiry.
