The Walk Across Kentucky

The Walk Across Kentucky was first planted in 1991 after extensive plant collection efforts in the 1980’s, which sought to secure the botanical diversity from across the commonwealth, and cultivate it in a common location for research and conservation efforts.  The collection currently exists as a two-mile paved pathway that meanders through over 80 acres of native plantings representing the 7 physiographic regions of the state.  The collection is constantly expanding, and as of 2015 includes over 520 native species from 99 plant families.   There are 2500 trees and shrubs on the Walk Across Kentucky, showing the great diversity of woody plants found in the state.  More recently, efforts have been made to further develop the interesting ecosystems found across Kentucky, including tallgrass prairies, wetlands, savannahs, and glades.  

The Arboretum Woods Walk

The Arboretum Woods is an especially valuable part of the collection.  It is frequently cited as one of the last remaining examples of inner-bluegrass woodlands.  The Arboretum Woods includes over 60 species of trees, shrubs, grasses, and wildflowers including some ancient trees aged over 300 years.   A half-mile mulched trail provides access through the woods, and we ask that visitors remain on the trail to preserve the forest understory.
