Sunseeker Carolina JessamineThis hardier cultivar of South Carolina's State Flower is terrific for both sun or quite heavy shade and produces gorgeous bright yellow flowers that accent its evergreen foliage for about 4 weeks in March or April. Plant at the base of fences, arbors, arches or walls. The vines will climb and support themselves by "twining" through lattice or chain link fences, but must be tied to larger posts until the plant reaches the top.
