Lanceleaf greenbrier is a native evergreen vine that can climb or sprawl extensively, reaching up to 20 feet in height and 10 feet in spread. It produces small greenish flowers in spring and develops blue-black berries that persist into winter. The thorny stems and vigorous growth habit make it better suited for naturalized areas than formal landscapes.
