With fall well under way and winter fast approaching I have taken to indoor projects, but, the garden is never far from my thoughts. One of the nagging problems that I just haven't been able to find a solution to is the ground cover issue. I live in USDA zone 4b. I would like to find a ground cover as short as possible that will survive ours winters (extra points for evergreen). Growing true mosses is probably not an option at this point as there is no shade. With a seemingly short list of plants, I am more interested at first to find suitable species and worry about leaf color and luminosity later. If everyone could be so kind as to share their thoughts and experiences that would be great!
