Abstract
Boxwood is a quintessential garden shrub that has been used in landscape design since ancient times. The beloved evergreen is an irreplaceable component of American gardening heritage and history as it has been used in garden design since the country’s founding. Today, many historic American gardens of the Colonial, Antebellum, and Colonial Revival eras retain historic boxwood that are irreplaceable. However, a devastating disease caused by the fungal pathogen, Calonectria pseudonaviculata, which targets Buxus sp. is threatening the future of boxwood in historic American gardens. This research evaluates boxwood blight best management practices used in historic American gardens and how it affects the integrity of the historic landscape.
