Where did apples originate in the U.S.?

Apples did not originate in the US. They were brought to America by the English colonists and carried along as they migrated west. The story of Johnny Appleseed is based upon the kernel of truth that a man named John Chapman planted Apple orchards throughout large parts of the Old Northwest Territory (Ohio, Indiana, Illinois, Michigan, Wisconsin) and that these orchards were used by later settlers who encountered them.
