The Snail Vine (Vigna Caracalla) is a beautiful vine and well worth growing. It is not very hardy. It generally dies back in winter, doesn't really do well below 50 or 40 degrees. Being a fast grower, it catches up the following spring, growing fast when the weather turns warm and twining up everywhere.
