I don't know about fragrance, but I believe there is a yellow sport of 'Westerland' in commerce. I believe 'Golden Showers' is fragrant, maybe? I am no fan and have never grown it. 'Roberta Bondar' is crown and partially cane hardy for me, has large very nicely shaped flowers but no fragrance. IMHO, 'Goldregen', from Noack, is a lovely rose, with large yellow flowers with ruffled petals, but only light fragrance. It does grow back for me every year so far. Depending on how it grows next summer, I would be happy to send cuttings to anyone interested. I would like to see it return to American gardens.
