They are hardy, but some are supposed to want more warmth than others to be really happy. I'm trying some of the moschatas, had no dieback last winter, however I talked to Uncommon Rose and they said they do have some dieback. So far, among the Teas and Noisettes, I've seen no winter dieback to speak of. Marechal Neil looks good, and that one is supposed to be quite heat loving. I'm getting most of my roses from Vintage.

Some doing well for me are Zepherine Drouhin, Crepuscule, Reve d'Or, Champney's Pink Cluster, La Biche, Sombreuil, Souvenir de la Malmaison, a couple of Gallicas, Cornelia, Penelope, and Mons. Tillier. Others are still too new or small to make a good report on, like Marechal Niel.
