Lush trailing foliage adds a feeling of exuberance and richness to summer hanging baskets and container planters, and many seek out "the best" trailers when planting their summer gardens. For those looking for a color other than chartreuse, consider 'Sweetheart Red' sweet potato vine. Heart-shaped leaves have a distinctive red tone and the more sun, the deeper the color. This variety will trail up to four feet in length, so plant it along the edges of hanging baskets or tall container planters for maximum effect.
