This hardy native of Japan and northern China was introduced to the U. S. in 1870
and is still popular in the horticultural trade. Its attractive berries are carried by
animals beyond garden plantings, allowing the vine to spread into natural areas
where it can climb to heights of 20 feet or more. It is reported as invasive
throughout the mid-Atlantic region and in nearby national parks.
