Evergreen: The Gala for The Morton Arboretum is the annual fundraising event to support the institution’s mission to plant and protect trees for a greener, healthier, and more beautiful world. The gala advances the Arboretum’s leading-edge science, benefiting trees locally and globally as they face increased threats. In 2020, the event raised more than $400,000 in funds for tree-focused research, outreach, and programs. Evergreen supports the organization’s enduring impact and contributes to the preservation of the Arboretum’s beauty and value for generations to come.
