Situated at the southeast corner of the U.S. Capitol grounds, the U.S. Botanic Garden immerses visitors in 65 acres of themed gardens and climate-controlled conservatories. From arid desert cacti to tropical orchids, carnivorous bog plants to regional native meadows, the Garden showcases the diversity of plant life and our relationship to it. Self-guided tours, docent-led “Plant Chats,” and seasonal exhibitions make it a verdant oasis in the heart of Washington, D.C.

What to Expect

Enter through the Conservatory’s grand central pavilion to discover four climate zones: the Desert House (cacti, succulents), the Orchid House (rare orchids), the Tropical House (bromeliads, palms), and the Fern/Medicinal House (ferns, ethnobotanical specimens). Outdoors, the National Garden features the Rose Garden, Butterfly Habitat Garden, Four Seasons Garden, and the Regional Garden highlighting Mid-Atlantic native species. Interactive displays explain pollination, seed dispersal, and plant conservation efforts, while the Bartholdi Fountain plaza offers a shady café and demonstration garden.

Background and Cultural Context

Chartered by Congress in 1820, the Botanic Garden’s conservatory was completed in 1850 by architect Robert Mills. Its mission—to explore, conserve, and display plant diversity—has guided expansion from a small greenhouse to its current integrated indoor-outdoor campus. The Garden collaborates with USDA research, endangered-plant recovery programs, and educational outreach to promote horticultural science and sustainability.

Annual exhibitions—from bonsai retrospectives to holiday train displays—draw visitors of all ages. The Garden’s Living Plant Collections database and seed bank support global botanical research and the preservation of rare species.

Best Time to Visit

Weekday mornings (9–11 AM) offer serene greenhouse exploration before school groups arrive. Spring (March–May) brings cherry-blossom companion plantings and peak bulb displays. Summer weekends host outdoor concerts in the National Garden. Late autumn features chrysanthemum shows; winter holiday train and model-railroad exhibitions run December–January, with the conservatory aglow in festive lighting.

The Garden’s entrance is at 100 Maryland Avenue SW. Metro: Blue/Orange/Silver to Federal Center SW station, then a 5-minute walk east. Circulator buses and Metrobus routes serve Maryland Avenue.
