VISIT

WHAT TO SEE

The US National Arboretum is a research institution, public garden, and green oasis of 451-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. 

Arboretum Collections

In addition to the collections described below, the Arboretum contains striking collections of boxwoods, daffodils, daylilies, dogwoods, hollies, lilacs, magnolias and maples.

This tribute to the history and beauty of bonsai is home of hundreds of bonsai trees, some of which are centuries old. The Museum has reopened but the Tropical Conservatory and Exhibits Gallery remain closed.
