Welcome to the Polly Hill Arboretum



The Polly Hill Arboretum, a Martha’s Vineyard horticultural and botanical landmark, was developed by the legendary horticulturist, Polly Hill (1907-2007). Here in 1958, Polly began an arboretum by sowing a seed, eventually bringing 20 acres under cultivation while preserving 40 additional acres as native woodland. Established in 1998 as a nonprofit institution, the Arboretum is devoted to the cultivation and study of plants and the preservation of the character and magic of this tranquil landscape.


Rare trees and shrubs from around the world are set among stone walls, meadows, and fields, including Polly’s famous North Tisbury azaleas, the national stewartia collection, camellias, hollies, rhododendrons, crabapples, conifers, magnolias, and many more. The kousa dogwood allée, perennial border, monkey puzzle tree, and the Julian Hill magnolia are favorites with visitors.
