One of the most outstanding features of the estate that became the Morris Arboretum in 1933 is the collection of large and stately trees placed throughout the 92-acre property. These sovereigns form the fabric that weaves together the Arboretum. Beginning with founder John Morris's interest in growing plants from around the world, unusual specimens have flourished on the site of the Morris Arboretum for well over 100 years.

Today, we continue the Morrises' legacy by caring for our mature trees and continuing to expand our tree collection. These 17 trees are a sampling of the most outstanding and beautiful trees throughout the Arboretum. They represent the diversity of our plant collections by showing plants from North America, Europe, the Mediterranean, China, Japan, and Korea. Some of them are among the largest of their kind in North America. Others are exceedingly rare and may be among only a handful grown outside of Asia. Others are unusual horticultural forms. What all these awe-inspiring specimens share, is a connection to our past, hope for our future, and a testimony to the beauty and longevity of trees.
