Living Connections: The Arnold Arboretum and Korea
Plants and people are at the heart of "Living Connections: The Arnold Arboretum and Korea," a new exhibition that explores more than a century of connections among science, history, culture, and international partnership. Opening October 24, 2026 in the Hunnewell Building Visitor Center, "Living Connections" examines the Arnold Arboretum’s enduring relationships with the flora, landscapes, and people of Korea. The exhibition pairs plants from the Arboretum’s living collections with one of the most extensive surviving visual records of early twentieth-century Korea, including photographs, archival materials, and contemporary collaborations.

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.
