Comprising over 265 acres of land that span several neighborhoods, the Arnold Arboretum is one of the last, and largest pieces of Frederick Law Olmstead’s Emerald Necklace. The mission of the Arboretum is to increase knowledge of biology of woody plants, and dedicates a host of hands-on botanical and horticultural education sessions . Here, Eastern White Pine meets the natural environment in the form of a new visitor and education center: learning becomes informed and inspired by the environment.
