@MIchael Hibberd you post these fabulous pictures of your orangery that the rest of us can only dream about. It is beautiful, thanks for sharing that little bit of your world with us. I'm with Mary, it looks like a wonderful place to have a cup of tea and something to read.
I know only that thy are a red 'wine' grape and not eaters. The year before last (I moved here just before then) they produced a crop but it caught a fungus of some description. It had been sorted, but then next year some builders cut it back to a small stump at an awkward time in their ignorance. So, this year is perhaps the first I can truly investaigate and potnetially use them.
I will let you know as soon as!
I was recently also given cuttings from a white grape vine, again of unknown variety, and have a couple of hardwood cuttings and a few soft so fingers crossed.
