The Morton Arboretum is a magnificent outdoor museum with a mission to collect and study trees, shrubs, and other plants from around the world, to display them across naturally beautiful landscapes for people to study and enjoy, and to learn how to grow them in ways that enhance our environment. Our goal is to encourage the planting and conservation of trees and other plants for a greener, healthier, and more beautiful world. The Arboretum ranks among the leading arboretums of the world in size, age, quality of specimens, and programs in Plant Collections, Science and Conservation, and Education.
