Thunbergia alata 'Yellow'
Yellow Black-Eyed Susan Vine: Evergreen vine that sprawls along the ground and clambers up on anything that will support it. The twining stems will reach 6-8 feet and are covered with nearly year-round, yellow tubular flowers with (almost) black throats. Sometimes treated as an annual, it is perennial in frost free areas. Full sun to part shade and medium water.
