Securing the future of trees

For a greener world

The Arboretum’s vision—of  a greener, healthier, more beautiful world where people and trees thrive together—has never been more important.

Science is the foundation of the Arboretum’s work for trees—and guest admissions, memberships, and donations fund important work that has an impact in the Chicago region and around the world.

Collections Research

The Morton Arboretum’s living plant collections and dried herbarium specimens represent one of the most significant collections of cold-hardy trees and shrubs worldwide. These collections are a major resource for researchers to understand global plant diversity, what different plant species need to be healthy, grow, and reproduce, and how to conserve plant species and restore plant communities.
