Many aquarium plants are actually marginal plants that in nature grow out of the water. Ludwigia, bacopa, pennywort, and rotala can also do well depending on the actual light levels involved. Clearly they can all take as much water as you want to throw at them. Pennywort at least can be a bit of a pest in a vivarium because it grows quickly and can take over. Similarly hydrocotyle tripartita will do the same.
