United States Botanic Garden-living plant installations and Conservatory

The United States Botanic Garden, located adjacent to the U.S. Capitol, maintains living plant collections in its Conservatory, outdoor National Garden, and Bartholdi Park for public display, research, conservation, and education. The institution traces its congressional origins to the early 19th century and is operated by the Botanic Garden staff under the Congress-established authority. The Conservatory and outdoor display gardens are permanent horticultural installations open to visitors year-round.
