About the Arboretum

Trails and paths wind through mature trees

When Joy Morton established The Morton Arboretum in 1922, he envisioned a “great outdoor museum” of trees. Today, our living collections inspire visitors to appreciate, learn about, plant, and protect trees. The Arboretum champions the world's trees through plant collections, science and conservation, education, and outreach.

The Morton Arboretum's 1,700 acres hold more than 222,000 live plants representing nearly 4,300 taxa from around the world. Situated on the rolling Valparaiso moraine and bisected by the East Branch of the DuPage River, the Arboretum is planned and planted to nurture and display trees and shrubs in environments conducive to their growth.

The Arboretum conducts leading scientific research on tree health and tree improvement, collects and displays trees for study and enjoyment on the grounds, offers educational programming for adults and children, and presents nature-related activities year-round for people of all ages and interests.

Also on the grounds are the Visitor Center with The Arboretum Store and Ginkgo Restaurant and Café, four-acre Children’s Garden, one-acre Maze Garden, Sterling Morton Library, Plant Clinic, nine miles of roads, and 16 miles of trails.
