Existing comment: The Chinese Hackberry Tree
Witnessing a Century of Change

This tree has seen many changes. Planted around 1905 on the grounds of what was then the U.S. Patent Office Building, it has slowly grown as the city has developed and transformed around it.

A rare, large, local specimen of a Chinese hackberry (Celtis sinensis), it has witnessed the relocation of Chinatown from its original site on Pennsylvania Avenue; rioting, looting, and burning during the 1968 riots; the opening of the Smithsonian's National Portrait Gallery and American Art Museum; the rise of Chinatown as a major entertainment and sports destination; and many other momentous events in the history of our nation's capital.

About the Chinese Hackberry
The Chinese hackberry (Celtis sinensis) is native to China, Korea, and Japan, where it is often found on forested slopes. It is a member of the hemp family (Cannabaceae), along with marijuana and hops.

"One of the prettiest shade trees in Japan, suitable for avenues or private gardens, parks, etc. . . . It should be tried in the Southwest as a shade tree."
-- David Fairchild, Agricultural Explorer, U.S. Department of Agriculture, 1903

ca. 1971
The Smithsonian acquired the former Patent Office Building in 1962. After extensive interior renovation, the National Portrait Gallery and the Smithsonian American Art Museum opened to the public in 1968. The Chinese hackberry is pictured at center.

Today
At more than 115 years old, the Chinese hackberry remains healthy and strong, with a trunk diameter of nearly four feet. Who knows what it will witness in years to come?
