The Champion of Trees

The Morton Arboretum celebrated 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 developed a beautiful new garden and planted more than 3,000 trees throughout the Chicago region.

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.
