The arboretum is home to thousands of trees and shrubs, with species originating from all around the world. Expect oaks, pines, maples, and many more. In addition to the purely natural flora, Arnold Arboretum is also home to several curated gardens that showcase different plant collections. The park is also home to sections of meadow and wetland, so there's plenty of fauna to go with the flora!

There is also cultural interest to be found in the park, including the Hunnewell Building and Visitor Center, the Larz Anderson Bonsai Collection, and the Weld Hill Research Building. These buildings and collections offer insights into the arboretum's rich history and ongoing research efforts.

Not many places combine the natural with the urban as well as Arnold Arboretum!
