I like what Celeste in NH, zone 4 wrote about this rose:
"celeste(zone 4 NH)
If someone was twisting my arm and forced me to choose JUST ONE, even though I adore the scent of dozens of my lovelies, I would have to cry out 'Felicite Parmentier', that sweetly-scented alba from heaven. It would be a near-tie with 'Great Maiden's Blush', and then third would be my namesake rose 'Celeste'. For me, there is nothing to compare to the divine albas for fragrance. If you've never had the pleasure of inhaling the pure sweet bliss of the albas then you are missing out.
After that, I could name dozens that I stick my nose into all summer that are intoxicating. Yolande d'Aragon, Mrs. John Laing, Heinrich Schultheis, Pierre Notting, Belle Amour, Comte de Chambord, Alba Maxima, Ispahan, Boule de Nanteuil, Rose de Rescht,
Marchesa Boccella, Johasine Hanet, Louise Odier, Baron Girod de l'Ain, Stanwell Perpetual, Autumn Damask, Souvenir du Pres. Lincoln, Queen of Denmark, Chloris,
Pompom Panachee.....the list could go on and on.
For modern roses, my favorite by far is Frederic Mistral, followed by Amazing Grace, Pope John Paul II and Rouge Royale." Celeste in NH (zone 4).
