Walk along grass paths and discover a diversity of over 2,200 different trees and shrubs representing 486 species, hybrids and cultivars.

Visit for wellness, play, and enjoyment as you learn about the natural world of trees. Learn about trees that you might include in your landscape when you observe different varieties and selections side-by-side. Common and scientific names are found on the tags of each tree and shrub for easy identification.

Tree and shrub collections at the arboretum exist for our quiet enjoyment of the natural world, to enhance our knowledge of horticulture, botany and ecology, to demonstrate sound conservation and to provide research opportunities.

The Brenton Arboretum is a 501(c)(3) non-profit museum, and special type of public garden dedicated to trees and shrubs.
