Evergreen, twining vines up to 20' long, produce clusters of 2" yellow-centered, red, trumpet-shaped blooms starting in mid-spring. Red berries follow. Paired, blue-green leaves are fused at the base. Woody stems have papery, orange-brown exfoliating bark. Native ME to IA and south to TX and FL.
Tolerates dry soil. Not overly aggressive, it can be used as a groundcover as well as a climber. Bloom is heaviest in full sun. Blooms on old wood so prune just after flowering.
