Last fall i planted Pohjole's Daughter. It is supposed to be a low and spreading large leafed rhodi. It is listed in the DG plant files. Mine was a sick one that the Home Depot buyer gave to me for free. I'd send you a cutting if I were a little more confident of the plant's health at this time. Weston Nurseries in Hopkinton MA sells it for a much bigger price, so it is in distribution. Maybe this variety will do the job for you. Where I live its hardiness is important and it is hanging on.
