This twining, flowering vine looks like a morning glory and even up close, the flowers are quite similar. The tubular flowers of the sky flower vine are a little deeper, about 3 in long, and are borne in drooping clusters. The most commonly seen varieties are sky blue to light violet although there is a white flowered type as well. Leaves are leathery and have a distinctive elongated heart shape. The plant grows fast in warm weather, easily covering a trellis or large section of fence in one season. It is one of the freest flowering vines for shade in the South and is underused due to lack of distribution. Growth slows or stops in cool temperatures, and the top is killed to the ground after a freeze. In frost-free climates, it is evergreen. This vine is an easy to care for plant that can quickly cover a fence or pergola. The gorgeously showy flowers and lush foliage make this a choice addition to any garden.
