The “Crown Jewels” of the Washington Park Arboretum
A tribute to our late Director, Dr. Sarah Reichard. May she forever garden in peace amongst a grove of Stewartia, her favorite tree.
[Editor’s Note: If you have time to experience their true beauty, it is highly recommended you visit our Stewartia Collection. The smart phone version of our interactive map can be used to pin-point specific locations and information for mature specimens of the species listed below.
