Arboretum

Did you know the Zoo is home to hundreds of plants and trees from around the world? As an accredited Arboretum, we care for more than 850 trees and shrubs representing over 160 species. From towering native oaks and historic elms to ancient ginkgo trees and colorful flowering shrubs, the Zoo's plant collection is every bit as diverse and fascinating as its animal residents. 

Some of the trees you'll see during your visit are more than 100 years old, including a row of elms near the Zebra Entrance that date back to the original Franklin Park landscape. Keep an eye out for mighty Northern red oaks, whose acorns feed wildlife and whose branches support hundreds of species of moths and butterflies, as well as endangered trees such as ginkgo, green ash, American elm, and star magnolia. In the historic Rock Garden (opening soon!) you’ll discover blueberries, winter heaths, and other plants as the space continues its restoration.
