The U.S. National Arboretum is a collections-based research facility and public garden of the U.S. Department of Agriculture (USDA). It is dedicated to the enhancement of the economic, environmental, and aesthetic value of ornamental and landscape plants through long-term, multidisciplinary research, conservation of genetic resources, and interpretive gardens and exhibits.
Established in 1927, the U.S. National Arboretum is part of the Agricultural Research Service (ARS), the principal in-house research arm of the USDA. The ARS conducts research to develop and transfer solutions to agricultural problems of high national priority to ensure high-quality, safe food and other agricultural products. It also assesses the nutritional needs of the American population to sustain a competitive agricultural economy.
We had a great time exploring the U.S. National Arboretum. It was educational and interesting at the same time.
To find the Arboretum, take Exit 19 off the DC Beltway (on the east side of town) and take Rt 50 east about 7 miles.
