Hi Chuck! Prior to my move to Idaho, I was in zone 5a. I always stayed away from evergreens, thinking that they would never survive in my cold climate. I finally did buy some, and was very surprised at how well they adapted! However, I bought from a local grower who had the plants in her garden for a few years first, so they were well tested. The majority of them behaved as a dormant. If at all possible, I'd suggest buying evergreens from a local grower, who has already tested them out to make sure that they can withstand much colder conditions that are specific to your area.
