Answer: Your new snowball bush (Viburnum opulus) is hardy in zones 4-8 so it will survive your winters without problem. I wouldn't wrap the branches, but I'd mulch over the root area just to keep them protected this first year. If there's any winter damage evident next spring, prune it off to encourage healthy new growth. I've successfully grown snowball bush in my Seattle area garden without problem, even when we've had snow and blustery winds. I'm sure yours will be just fine this winter. Enjoy!
