Plants & Collections

Maple-leaf Oak

Scientific Name
Quercus acerifolia

At the southern tip of the Arboretum stands the oldest maple-leaf oak in cultivation.

Pecan

Scientific Name
Carya illinoinensis

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.
