American barberry

Description

Berberis canadensis, commonly known as the American barberry or Allegheny barberry, is a member of the family Berberidaceae. Berberis canadensis is one of only two simple-leaved or 'true' Berberis indigenous to the United States. The other is B. fendleri of the southwest U.S. The epithet "canadensis" literally means "Canadian" but was often used by 18th-Century botanists to refer to any plants growing in northeastern North America.
