Memorial Arboretum: Trees

Fall foliage at Memorial Arboretum

Arlington National Cemetery is home to an extremely diverse and significant collection of trees and landscapes. Its more than 9,000 trees include approximately 400 varieties and species, both native to the area and exotic. Some of the cemetery’s oldest trees, at nearly 250 years old, pre-date the first burials. Many trees have been planted and/or dedicated by U.S. presidents, visiting dignitaries, military organizations or the families of service members.

In addition to four state champion or co-champion trees, trees of particular interest include 142 memorial trees, the Medal of Honor historic trees and many magnificent specimen trees.

The purpose of the Memorial Arboretum is to research, document and interpret the stories behind the cemetery's trees and landscapes. We invite you to explore these hallowed grounds in every season.
