Other info. - This nasty and aggressive species was brought to North America in 1855 as an ornamental. It has since spread rapidly and is found over much of the eastern half of the U.S. from Kansas east. The berries are eaten by birds which helps the plant spread rapidly. There are other species of bush honeysuckles in Missouri but this is the most aggressive and common.
