The United States Botanic Garden (USBG) is a living plant museum. Exhibits interpret the role of plants in supporting earth's diverse and fragile ecosystems and in enriching human life. The Conservatory and surrounding terraces, Bartholdi Park, and National Garden are open to the public. Established by Congress in 1820, the U.S. Botanic Garden is one of the oldest botanic gardens in North America. The Garden has been administered through the Office of the Architect of the Capitol since 1934.
The Conservatory houses permanent collections of plants from subtropical, tropical, and arid regions and showcases orchids, medicinal, economic, endangered, and Jurassic plants. From late May to mid-October, the Conservatory Terrace features displays of thematic container gardens.
Bartholdi Park is across Independence Avenue from the Conservatory. Here visitors will find a tapestry of theme gardens surrounding the historic Bartholdi Fountain. The gardens suggest interesting plants and designs at a scale suitable for the home landscape.
The National Garden is adjacent to the Conservatory. It features a Mid-Atlantic native plant garden, Rose Garden, First Ladies Water Garden, Butterfly Garden, and Amphitheater.
