Experience quiet enjoyment at a living museum of trees, shrubs and native prairie. Walk along grass paths and discover a diversity of over 2,200 different trees and shrubs representing 486 species, hybrids and cultivars. Bathe in sunlight or keep cool under a leafy canopy as you gaze over vistas of crabapple blossoms, silhouettes in the sunset or fantastic autumn hues.
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.
