I am really surprised actually, about how well Mrs. Herbert Stevens does here. When I bought her ~10 years ago, I had my doubts about it, after all she is an old hybrid tea and I am in wet and cool seaside Dutch climate. She did get quite a bit of frost damage in the winter of 2010 (?) when we had temps dropping bellow -15C, but overall the damage was less than I expected, nearby Kordes roses suffered more (I lost Laguna then for example).

Also, I replanted Mrs. Herbert Stevens later on, in a bad spot in a shade, where she could climb its way to full sun - and she is doing surprisingly well, no bad foliage issues, good rebloom for an old rose, and tbh I do regret that placement, since she is one of the best white roses I have owned. I do notice the peach shading btw, as in the descriptions, so it can be climate related, then it fades to pure white. Much more delicate and graceful than Iceberg.
