Fun Facts

  • Several beautiful specimens of three-flowered maple (Acer triflorum) grow in front of the Hunnewell Building. While many maples have simple leaves (think sugar maple or red maple), A. triflorum has compound leaves composed of three leaflets. This maple develops excellent orange to red fall color and has attractive amber bark that exfoliates in narrow curls.

  • Just across the road from the Hunnewell Building is the original specimen of Acer rubrum ‘Schlesingeri’, a red maple cultivar introduced by the Arnold Arboretum. It is one of the earliest red maple cultivars to show fall color, often as early as mid to late August.

  • Over 85 feet tall and over 100 years old, the large silver maple (Acer saccharinum, accession 12560*C) along Meadow Road is a favorite with visitors and was the tallest tree at the Arboretum at over 130 feet in 2008. This tree survived the devastating hurricane of 1938 and has suffered branch loss due to storms over recent years including major damage by a winter storm in 2018.

  • The genus Acer holds a number of interesting examples of North American–Asian disjunct flora (closely related, similar-looking species that grow on separate continents). Among the Arboretum’s maples, note the similarities between the striking stripe-barked or snake-bark maples from Asia (including A. tegmentosum, A. davidii, and A. capillipes) and striped maple (A. pensylvanicum) from eastern North America.

  • The maple collection holds accessions of Japanese maple (Acer palmatum) and its cultivars, which are popular small ornamental trees. Similarly handsome species in the collection include Korean maple (A. pseudosieboldianum), full moon maple (A. japonicum), painted maple (A. mono), and hairypalm maple (A. pubipalmatum).

  • Paperbark maple (Acer griseum) has long been favored by plant connoisseurs for its lovely exfoliating, cinnamon-colored bark and bright red-orange fall color. The Arboretum holds two of the first paperbark maples in the United States, grown from seed wild-collected in China by E. H. Wilson in 1907; look for one venerable specimen in the heart of the maple collection, and a unique, wide-spreading specimen in the Explorers Garden on Bussey Hill.


The Arnold Arboretum has an extensive collection of maples (Acer spp.), containing 139 taxa (kinds), including 39 cultivars, from around the world. Because of its diverse and numerous holdings of wild-collected maples, the Arnold Arboretum is designated as one of the Plant Collection Network’s maple collection sites. Our collection is especially rich in rare and unusual Asian maples, including a number of endangered species.

Because of these valuable accessions, the Arboretum’s maple collection was ranked as the most significant in the world for conservation purposes in a report by Botanic Gardens Conservation International.
