Over the past century, The Morton Arboretum has made a significant impact for trees and people—studying, planting, and protecting trees; educating people; and welcoming millions of guests to its living tree and plant collections and its glorious landscapes. As it enters its second century, it is still growing strong, like a mighty oak, at a time when people need trees more than ever before. 

Evergreen: The Gala for The Morton Arboretum supports the organization’s enduring impact, advancing leading-edge science and preserving the Arboretum’s beauty and value for generations to come.  In 2021, the event raised more than $400,000 for tree-focused research, outreach, and programs. Join us in 2022 during the Arboretum's centennial year for a fundraising event like no other, including first access to The Grand Garden, the Arboretum's newest attraction!
