Berberis koreana: Korean Barberry

Korean Barberry is one of the most beautiful Berberis and it's not invasive.  The fall color is excellent and the fruits are nice.  Also, it has showy yellow flowers on gracefully arching branches in the spring.  It is stoloniferous so suckers keep coming up which enable easy propagation.  I have had mine for ten or fifteen years and have never yet seen seedlings.  It is possible that since I only have one, it would seed as the other barberries do if I had more than one clone but I have had no problem as yet.
