The U.S. National Arboretum was established in 1927 by an Act of Congress. The Arboretum is administered by the U.S. Department of Agriculture’s Agricultural Research Service to serve the public need for scientific research, education, and gardens that conserve and showcase plants to enhance the environment.
The arboretum has over 446 acres of trees, shrubs and plants and is one of the largest arboreta in the country. The gardens include a variety of exhibits from formal landscaped gardens to single-genus groupings. Arboretum staff also conduct wide-ranging basic and developmental research on trees, shrubs, turf, and floral plants.
