Well, I know it isn't really - at least, I don't know of Lewis Carroll ever visiting this garden. It's at Bridge End, Saffron Walden, now in the care of the local council, which does a great job. The garden was created about 15 or 20 years before Alice in Wonderland. I can't help feeling that Lewis Carroll must have had something in mind that looked like this - and the roses are all red, white or a mixture of the two!
