One of my favorite plants, Evergreen Solomon's Seal - Disporopsis perneyi http://davesgarden.com/guides/pf/go/37100/ would work in your situation. It may be a little taller than you're looking for, about 8"-12", but it will quickly form a carpet of glossy green foliage. PF says it's only hardy to Zone 7, but it has survived our Zone 6 winters for over 5 years. The evergreen foliage sometimes looks a little shabby by late winter and some years I cut it back hard before the new growth appears. Most years I don't have the time and just leave it and by late spring the glossy new growth quickly covers the old foliage.
