Answer: Sadly, I would not recommend boxwoods for a windy location in zone 4 or 5, it is too drying for them during the winter. Also, an exposed and windy site can make your location colder by a half a zone or more. So in my experience it would be unrealistic to expect boxwoods to perform well there. I would suggest you work with your county extension and/or local professional nursery staff to determine which evergreens would thrive in the area you want to plant -- taking into account wind, sun, soil, and your design goals -- and then select your favorite from among those.
