Plants & Collections
Maple-leaf Oak
At the southern tip of the Arboretum stands the oldest maple-leaf oak in cultivation.
Pecan
This pecan, collected in 1882, arrived from the first large research project undertaken at the Arnold Arboretum—a nationwide survey of trees and forests for the United States census in 1880. The collector was an ornithologist with an acute eye for detail.
