Facts

Bradford or Callery pear is native to Korea and Japan, and widely planted in North America for its abundance of white, early-blooming flowers and vase-shaped growth form. It is easy to grow, and is widely planted as a street tree. Its leaves turn gold to purple in fall. Although it rarely produces fruit, it has become naturalized in many areas throughout North America.
