What a positive way to look at losing plants, Jennifer! If we have good snow cover, I don't usually lose to many perennials,(most of the ones I plant are zone 3 or 4), but I do lose a lot of smaller trees when it is -20 or lower if we have it for an extended cold spell, but I bet your plants are mostly higher zones than that so would probably be more vulnerable? But if you had the snow before the bitter cold you might be surprised at what will survive it.
