Each garden and collection in the Arboretum is designed with a particular purpose in mind. For example, the Butterfly garden was designed to entice butterflies to visit the garden and feed on nectar. Aside from the joy of watching these beautiful insects fly among the pink and purple bee balm, pollen grains collected on their legs and wings help pollinate flowers, herbs, and other plants, throughout the arboretum.

The introduced trees and shrubs in the Arboretum are not arranged in a formal collection, but rather placed informally throughout the developed areas, especially among the gardens and collections. Overall, the arboretum's management and continued development follows this "naturalistic" approach rather than a formalized planting scheme. Many factors are essential to understanding and developing our "naturalistic" arboretum, including the interaction and sustainability of various wildlife habitats and corridors and the diversity of topographical, hydrological, and geological elements in the area.
