The United States Botanic Garden is a living plant museum on the National Mall at the foot of the U.S. Capitol. Bartholdi Park, named for sculptor Frederic Auguste Bartholdi, was created in 1932, and "serves as a home landscape demonstration garden and showcases innovative plant combinations in a variety of styles and design themes." Located on three acres west of the Conservatory site, the National Garden is "a showcase for unusual, useful, and ornamental plants that grow well in the mid-Atlantic region." "It provides "living laboratories" for environmental, horticultural, and botanical education in a contemplative setting. The major features of the National Garden are the Rose Garden, the Butterfly Garden, the Lawn Terrace, the First Ladies' Water Garden, the Regional Garden, and an outdoor amphitheater." The Conservatory is open daily from 10:00 a.m. until 5:00 p.m.
