I've heard & read that in Victorian times, the art of budding two or more different roses on a single root stock was not uncommon in those times! I even managed to do one myself several years back, although the the budding only lasted a couple of years!.......... (Apparently, I had budded it in the wrong place!) Now, my question to all you guys is, can you graft/bud etc a different colour/ type of Wisteria on the same root stock! Would be grateful if anyone knows about this, or anyone can tell me the lowdown on it! Regards, Ken.
