Thunbergia battiscombei - Blue Glory Vine

Rich purplish-blue, trumpet-shaped flowers are 3 inches long and have 2 inches open-faced petals, making it a very tropical looking plant. Some like to grow this one in a container so it spills over the edge. Can grow up to 6 ft if supported. Only hardy for zones 9,10 and 11, but worth trying for those that can.
