I'm fairly sure they're all grafted - all are from David Austin in Albrighton, although we have bought some from nurseries supplied by DA. I've been to Albrighton three times - as you would expect there is an amazing rose garden there - the problem is that every time I visit I come home with a car that looks like a mobile greenhouse...
I felt very pleased with my self-restraint at not having bought any more in 2015, until I went to a local nursery to buy a planter and left with six more DAs
Well, they were all half price and I did give two away as gifts, which perhaps justifies my lapse?
