The Hunnewell Building and Visitor Center at 125 Arborway are closed to the public in response to COVID-19. The Arnold Arboretum landscape is open dawn to dusk, though parking around the perimeter (except for handicap spaces) has been eliminated by the City of Boston and Commonwealth of Massachusetts. Please consider avoiding peak hours of visitation, wear a mask or cloth face covering at all times, and maintain at least six to ten feet of distance from others.

The Arnold Arboretum serves humanity as a premier destination for deepening understanding and appreciation of the plant kingdom. The Horticultural Library contributes significantly to this mission, stewarding a research collection of some 25,000 volumes on botany, horticulture, urban forestry, and more. The Library also houses the Arnold Arboretum Archives, which preserves and shares the Arboretum's history, its critical role in plant exploration around the world, and some 40,000 photographs. Although the library is closed to the public at the present time, our library staff is available to help with reference questions and material requests via email, and many resources including title listings, archival and contemporary photographs, and the complete run of our journal Arnoldia are freely accessible online.more »
See rare plants collected from around the world, breathtaking views of Boston, and both wild and manicured landscapes. This 281-acre jewel in Olmsted’s Emerald Necklace of parklands is both a research center of Harvard University and a beloved public landscape open free to the public every day.
The Arnold Arboretum of Harvard University is largely self-financed, funding its programs in botanical research, education, and horticulture through a private endowment built and maintained by past and present philanthropy.
