The problem for zone 5, where I am is that tender roses can survive the winters if well covered, but the canes still die and it takes long time for the bushes to grow back each year. Also the soil is damp and heavy, so the roots have push through that dense soil, and I don't really have a source for sand which would not be prohibitively expensive. Most HTs seem to need more heat than we typically have. Also, because the climate is damp. there is lots of BS pressure, and I don't care to spray. The HTs which seem to do best here are the large and vigorous Kordes HTs from the last decades of the 20thC.
