United States Botanic Garden

The United States Botanic Garden maintains 26,000 plant specimens in various climate-controlled rooms, each simulating different natural environments across the globe.

The garden's foundation traces to 1820 when George Washington, Thomas Jefferson, and James Madison established it, moving to its current location near the Capitol in 1933.

The Conservatory presents educational exhibits about plant life, environmental protection, and botanical research through ten specialized garden chambers under glass.

Located at 100 Maryland Avenue SW, the garden welcomes visitors daily from 10:00 to 17:00, offering free admission and wheelchair-accessible pathways throughout the facilities.

Four plants in the collection directly connect to the 1838 Wilkes Expedition, including ferns descended from specimens gathered during the global circumnavigation mission.
