Bartholdi Park , named for the sculptor of its historic fountain, is a garden demonstration landscape. Each garden is of a size and scale suitable for the urban or suburban home site. The gardens illustrate design principles and display plant combinations for a variety of themes and styles. Changing seasonal display beds feature outstanding annuals and perennials. Bartholdi Fountain , originally created for the Centennial Exposition of 1876 in Philadelphia, was moved to the Capitol Grounds in 1877 and to this site in 1932.
Visitors are welcome in the park every day of the year.
The National Garden will be constructed beginning in 1998 on the three acres of lawn adjacent to the Conservatory. Funds for its design and construction have been raised from private donations and revenue-producing activities of the National Fund for the U.S. Botanic Garden, a nonprofit 501c3 membership organization. Services of the U. S. Botanic Garden include a plant information hotline, an educational outreach program, and growing of plants for the beautification of Capitol Hill.
