All too often we forget that there are gardeners in the cold north who have winters with prolonged temperatures of -40F, low or no snow but drying winter winds and soil that heaves as it freezes and thaws. That kind of a climate requires tough plants that can really handle demanding conditions. The good news is that there are a lot of options for gardeners in the freezer of the north.
