Morton Arboretum

Situated on the rolling Valparaiso moraine and bisected by the East Branch of the DuPage River in the Chicago suburb of Lisle, The Morton Arboretum ranks among the leading arboreta of the world. Established in 1922 by Mr. Joy Morton, founder of the Morton Salt Company and son of J. Sterling Morton (founder of Arbor Day), the Arboretum encompasses 1,700 acres, including 500 acres of plant collections and gardens; and 900 acres of woodlands, prairie, meadows, lakes and streams.
The Morton Arboretum's living collections are one of the most comprehensive collections of woody plants in North America. On the grounds are 220,000 specimens in the collections and 4,500 different types of trees, shrubs and other plants native to 40 countries, which serve as vital resources for scientific study. Plant collections are categorized by horticultural, geographic, scientific, special habitat (modified soils/sites), evaluation groups, and endangered plants.

Since the Arboretum’s inception, practical, scientific research has been a cornerstone activity, focusing on how to grow healthier trees and to champion healthy tree communities all over the world so the planet can thrive. The Arboretum’s tree breeding program has introduced disease-resistant trees including the AccoladeTM elm (Ulmus davidiana var. japonica 'Morton’), State StreetTM Miyabe’s maple (Acer miyabei 'Morton’) and the Exclamation!TM London planetree (Platanus acerifolia 'Morton Circle’).
The Arboretum’s free Plant Clinic helps homeowners, gardeners and landscape professionals throughout the Chicago region and the world grow healthy, attractive, well-chosen plants. Trained staff and volunteers are available in person, by phone, or by e-mail to help with tree and plant selection, identifying and coping with pests and diseases, and other concerns.

Conservation is a cornerstone of the Arboretum. The Arboretum’s world-renowned 100-acre Schulenberg Prairie is one of the oldest reconstructed prairies in the U.S., while the Arboretum is leading and assisting efforts to prevent extinction and secure the world’s threatened tree species through its Global Tree Conservation Program.
