U.S. National Arboretum and the National Bonsai & Penjing Museum

The U.S. National Arboretum was established by Congress in 1927 and operates as a public research garden administered by the U.S. Department of Agriculture. Its living collections include extensive azalea plantings and the National Bonsai & Penjing Museum, both of which produce seasonal displays that draw local visitors. The arboretum runs educational programs, plant-research initiatives, and public exhibitions that contribute to the region’s horticultural culture.
