We visited York Gate before the Gardeners Benevolent Fund took over. Just me, DH and another couple being shown round by the owner. If it hadn’t been for the other couple, it would have been perfect 
I’ve always wanted to, but was confused because they are usually sold as grafted plants, and I thought it was the rootstock that determined the size? Not in roses, there isn’t much variety in rootstock or rootstock size. They’re not grown from seed because you want a bush that’s genetically identical to its parent, and grafting is quicker than cuttings for getting to a bush of sellable size.
For apple and other fruit trees, quick propagation of a tree identical to its parent is still importation, but the development of rootstocks that will keep the tree to a manageable size comes into prominence.
When we moved here, the front garden was a lawn, with a border of HT and shrub roses along the front, and tarmac path straight up the middle. So we got rid of the path and the grass, and set to planting to our taste, confident the roses would in due course give up the ghost. And so they have, with the exception of two dark red floribundas which flower from early summer through to the autumn frosts.
