How interesting, so good to hear the origins of this rose, as I first saw it at Peter Beales rose garden many years ago, labelled correctly as 'Toby Tristram', and I was in awe of it, a magnificent rose... I also saw it later on a wall at Mannington Hall in Norfolk, England.. a huge specimen, I think it's still there..

I think your Grandfather bred one fabulous rose, albeit a rather large growing one, that should be better known, where roses like Rambling Rector, Kiftsgate etc are grown..
