Are you wanting a vine to cover the ground or one to grow up onto a trellis in this area? For a groundcover in a moist area I'd suggest Golden Creeping Jenny, Lysimachia nummularia. This plant is evergreen, hugs the ground closely and spreads quickly over all types of soil. Some other possible groundcover choices might include English Ivy or Asian Jasmine. If you want something that climbs then you might consider the Crossvine, Bignonia capreolata 'Tangerine Beauty'.
