Black-Eyed Susan Vine
Tropical, typically twining plants noted for their showy flowers. Some of the perennial sorts grow fast enough to bloom the first season and can be treated as annuals. Those grown as perennials are evergreen in mildest climates. In cooler parts of the range, tops may be killed by light frost, but roots usually stay alive to send up new stems. Provide rich, well-drained soil. Good greenhouse plants.Thunbergia alata
