Holden Arboretum

At the Holden Arboretum, cultivated gardens come alive with color in the spring, cool forest trails offer a respite from the summer heat; woodlands are set ablaze with rich hues of fall, and paths lead you deep into the beauty of the winter woods.

Named as an Important Bird Area by the Audubon Society, with more than 20 miles of hiking trails, the Arboretum is a haven for bird watchers as well hikers, gardeners and nature enthusiasts.

Covering 3,600 acres, the Holden Arboretum is among the largest arboreta in the United States. Documenting more than 120,000 plants, the Arboretum’s horticultural focus is on a recognized collection of trees and shrubs, which are displayed in gardens accompanied by groundcovers and perennials, and in themed collections. We collect and display a diversity of plants and trees for evaluation and educational purposes, in order to convey sustainable plant choices recommended for our region. By sustainable, we mean plants that are adapted to our soils and climatic extremes, free from chronic diseases and significant pests, and non-invasive of natural areas. Plants include rhododendrons, magnolias, maples, conifers, nut trees, wildflowers, lilacs and viburnums. A visitor center, reference library and picnic area are on the grounds. Holden connects people with nature for inspiration and enjoyment, fosters learning and promotes conservation.
