non invasive ground cover in wet soil and almost no direct sun
the sides of my house face north and south. on the south side the ground is almost constantly wet with about 4ft from house side to neighbors fence. the north side is wider between house and neighbors fence but still has about 4ft that doesn't get much sun and stays wet. what non invasive ground cover - flowering or not - would you recommend for me? I live in Owasso Oklahoma (approx. 15miles north of Tulsa), zone 7?
