1. Thunbergia (Black-Eyed Susan Vine)
Commonly known as Black-eyed Susan vine, this annual is a beautiful choice for hanging baskets or for containers where you can provide some sort of trellis or stake. The heart-shaped leaves are accented by five-petaled flowers in white, cream, yellow or orange with the deep-maroon central eye. Some rare varieties have rose or variegated petals. Thunbergia also makes a great flowering plant for indoor gardeners, so you may want to bring yours in for the winter.
