Seckels are believed by many to be the only truly American variety of pear in commercial production. Unlike other varieties developed in the U.S. from a cross or bud sport of other European cultivars, Seckels are thought to have originated as a wild seedling near Philadelphia. They were discovered in the early 1800's. This may or may not be true, however. It is possible that German imigrants travelling westward through the area dropped fruit or left seeds behind.
