Plants & Collections
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.
Golden Larch
This rare native of East Asia puts on a golden show each fall before losing its needles. This specimen came to the Arnold Arboretum by way of the nearby Hunnewell Estate Pinetum in Wellesley, Massachusetts.
