U.S. Capitol Grounds Now an Accredited Arboretum

Friday, February 17, 2017

The United States Capitol Grounds was recently named an accredited arboretum. The grounds are now listed in the Morton Register of Arboreta, a comprehensive list of arboreta and public gardens that have a substantial focus on woody plants for the benefit of the public, science and conservation.

As a Level II arboretum, Capitol Grounds is recognized as an area with at least 100 species of woody plants, dedicated staff, enhanced public education programs and a documented collections policy.  

"The diligent efforts of Capitol Grounds are evident to all who work at and visit the Capitol campus. I am proud that the team's hard work was recently recognized by the Morton Register of Arboreta," said Stephen T. Ayers, Architect of Capitol.

Capitol Grounds encompasses more than 270 acres of land. The grounds immediately surrounding the U.S. Capitol Building cover an area of approximately 58 acres and provide a park-like setting for visitors, staff and Members of Congress. The grounds were designed in the late 1870s by Frederick Law Olmsted, a pioneer in the development of public parks in America.
