Lance-leaf Greenbrier is a native plant that has bright green, leathery leaves and small, light green flowers. This high climbing vine is valued for its shiny evergreen foliage. It is a great vine for trellis, porch, or cut for long lasting decoration. Female plants have green berries which turn red and then black when mature. It is mostly thornless except on young shoots near the ground. It grows from a large potato-like tuber and new shoots grow rapidly in spring once the root system is established. Plant in site with sun to part shade and in sandy garden soil. It will need a support to climb on. It climbs by tendrils which wrap around small diameter objects. Foliage on mature stems is oval but young shoots may have arrowhead shaped leaves.
The seeds have a period of dormancy. They can be planted outdoors in the fall or winter for spring germination or they can be cold stratified to simulate winter conditions and to break their dormancy at any time of the year.
