Salix babylonica
Abingdon is known as the birthplace of Eleanor "Nelly" Parke Custis Lewis (March 31, 1779 – July 15, 1852), a granddaughter of Martha Washington and a step-granddaughter of United States President George Washington. Published accounts have credited Abingdon as being the home to the progenitor of all weeping willows ("Salix babylonica") living in the United States. Ronald Reagan Washington National Airport, which occupies part of Abingdon's grounds, contains indoor and outdoor displays that commemorate the plantation's history.
