WHAT TO SEE
The US National Arboretum is a research institution, public garden and green oasis of 446-acres that sits on the shores of the Anacostia River in Washington, DC. Annually, over 650,000 visitors enjoy connecting with nature, plants and science. Its science has resulted in important plant introductions resistant to disease and pests that benefit our nation’s plant nursery landscape.
Established in 1927, the Arboretum is administered by the Agricultural Research Service (ARS) within the US Department of Agriculture.

Pandemic Guidelines
Statement from the Agricultural Research Service: Policy on Mask Use and Social Distancing

While this safety plan is being developed, the U.S. National Arboretum will follow the advice of public health and science experts, by requiring all USNA visitors and employees to wear a mask, maintain social distance while on USNA property, and to take other related precautions recommended by the U.S. Centers for Disease Control and Prevention.”
