All I can say is thank God for the snow cover. Hope the crowns of my mostly own root roses will survive. On the rose beds, except for Therese Bugnet, all are mostly covered.However, my guess is lots of cane damage come spring.
I had moved some potted roses into the raised bed veggie garden last fall, joining some that had been there for two years, since "my eyes are bigger than my stomach" when it comes to buying roses, and there just isn't any place for them in flower gardens yet. There is a rugosa Hansa, DA Graham Thomas, DA Glamis Castle, gallica Cardinal de Richelieu, and a few Rogue Valley Roses mystery roses. And looking out over the north side of house, towards those raised beds, I can see all their canes above the snow.
I guess we'll see who likes Zone 5 southern NH!
