Hello Home and Garden Info, I planted Virginia Bluebell (Mertensia virginica) bare roots in pots this month, but I am wondering which site would be better to keep the pots during the winter: 1) In my unheated garage, which averages about 35 - 45 degrees (F) during the winter and has several small windows for light. However it never goes below freezing in the garage. 2) On my outdoor deck, either tucked up against the house or further out along the deck railing. Obviously, the pots would experience ambient outdoor temperatures on the deck. My questions and concerns are whether Virginia Bluebells need freezing temperatures during winter to stay dormant and whether they need light (and naturally lengthening daylight of late winter and spring) in order to break dormancy. I would be worried about stretches of warmer than normal temperatures in the garage (which could get up to 50 degrees or more) causing premature sprouting. But alternatively I would want to know if the Virginia Bluebell roots could survive temperatures down in the teens, that can occur during winter cold snaps around here.
