I call this one "Gelli Aur" (pronounced, roughly - Gethly Ire in Welsh). I was given a cutting of it and it will happily root if it touches the ground, so I have several more in planters and have planted 3 out the front too.
It flowers once, in May, heavily scented, single white petals with a touch of pink at the edges when in bud. No hips I can remember. Grows quite strongly and vigorously.
Any suggestions? It's not in any of my David Austin catalogues and I can't find it searching on line.
