Comments: In warm climates this is an evergreen vine, but in most places it has a winter dormancy but returns the following spring following light freezes. This vine works well on garden structures and in hanging baskets and other raised containers where the vine can trail over the sides of the containers or planters. It will grow in partial shade but not bloom as freely as when growing in sunlight.
