The Edith J. Carrier Arboretum (Arboretum) is a 125-acre urban botanical preserve located within the city of Harrisonburg and the campus of James Madison University (JMU). It provides an ideal combination of naturalized botanical gardens (33 acres) and forest (92 acres), complementing each other and serving the purposes of research, teaching, and demonstration. This green space is home to a diverse ecosystem featuring native plants of the mid-Appalachians (woodland wildflowers, azaleas, and rhododendrons); a collection of non-native trees, shrubs, and bulbs (magnolias, Kousa dogwoods, hollies, daffodils, etc.); an Oak-Hickory Forest; a lowland swale; a shale barren; herb and rose gardens; a pond habitat; and a wetlands garden. An outdoor amphitheatre, terraced gardens, a Pavilion, a Monarch Way Station, and the Frances Plecker Education Center (Education Center) enhance the complex further.

The only arboretum located on a public university campus in Virginia, the Arboretum is a haven in the middle of urban growth and development, a place where nature can be honored, appreciated, protected, and studied. The Arboretum is a center for the conservation, enjoyment, and interpretation of plants and ecosystems of the Shenandoah Valley, and serves as an outdoor biology laboratory and environmental educational center with tours, lectures, seminars, workshops and other public programs. Four full-time staff, five part-time staff, and work-study interns help keep the Arboretum thriving.
