I live in zone 5 and though I haven't experimented with in-ground overwintering, I doubt any variety other than basjoo will survive winters here even with lots of ground cover. It's not unusual to see temps of -10F during winter (coldest I've seen was -37F) and sustained below zero temps for a month or more. I would suspect with ground cover AND heating cables, there might be a chance for quite a few varieties, but ground cover alone just won't do it.
