The Hartman Arboretum is located NW of Evansville. It is one half mile north of State Road 66, Diamond Ave, at Cynthiana Road, near the German Township Booster Club.

The Hartman Arboretum was founded in 2001 to provide an outdoor classroom for schoolchildren, as well as a place where other visitors could enjoy nature and learn about the diversity of trees and shrubs found in Southern Indiana. 

The Arboretum has about 500 trees of all varieties, including 15 different Redbud cultivars and 18 types of Oaks. Other areas of interest include the Wildlife Garden which was planned and developed by Master Gardeners and includes nectar plants and host plants for a multitude of butterflies.
