Centennial Celebration

The Morton Arboretum is growing strong
into its second century

The Champion of Trees

In 2022, The Morton Arboretum will celebrate 100 years of planting and protecting trees for a greener, healthier, and more beautiful world.

Over the past century, the 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. To commemorate this milestone, the Arboretum is developing a beautiful new garden and is committing to planting more than a thousand trees throughout the Chicago region. You can look forward to a variety of special events and educational programs throughout 2022 to celebrate the centennial.

The Grand Garden

A grand new garden will open in September 2022 for enjoyment throughout the Arboretum’s second century. Showcasing lush, colorful plantings and delightful water features, this splendid garden will be a central space for celebration and joy.

Watch The Grand Garden take shape and make a gift.

Trees for the Next Century

In 2022, The Morton Arboretum will plant more than 1,000 trees throughout the seven-county Chicago region. Over the next century and beyond, these trees will grow and spread their branches, making communities beautiful and improving people’s lives.

Founded in 1922 by
Joy Morton

When Joy Morton established The Morton Arboretum, he envisioned a great outdoor museum of trees. A century later, his vision is shared with millions of people who come to the Arboretum to experience the benefits of spending time among trees and plants, to learn, or to create. Morton recognized a need for a place where trees could be treasured and studied for the well-being of people and the environment. That need is just as strong today.
