The property's history began in 1681, when William Penn signed a "lease and release" agreement with Thomas Minshall, an English Quaker, for property in Pennsylvania that contained the site now occupied by the arboretum.

The arboretum itself started in 1825 when two brothers, Jacob and Minshall Painter, set aside land to systematically plant more than 1,000 varieties of trees and shrubs.
