      Olmsted and the Arnold Arboretum

      Frederick Law Olmsted, considered the father of landscape architecture, designed some 500 public spaces in North America. The Arnold Arboretum is the only arboretum he designed, a National Historic Landmark, and a model for others around the world. Docent Bill Beizer, will identify the elements of the Arboretum that best reflect Olmsted’s philosophy and approach to landscape design.

          Autumn in the Arboretum

          Autumn is one of the most beautiful times of year at the Arboretum, with leaves changing color and all sorts of unique seeds and fruits appearing on the branches. Join docent Vicki Amalfitano for a tour to learn about all the changes that happen in the Arboretum’s collections in the fall.

              Docent Katrina Scott will lead this interactive tour with stops for moments to reflect on specific trees and the stories associated with them. Were they revered or feared?  A home for deities or tricksters?  We will begin at the Walter Street Gate to visit the oldest ginkgoes at the Arboretum, then head up the Conifer Path and diverge to walk, rest, and reflect among various conifers, eventually ending by the yews near Bussey Brook and Hemlock Hill Road.

                Oak Collection Tour

                Oaks have been more closely associated with the development of human civilizations across the northern hemisphere than any other genus of tree. From the Royal Oak to the Charter Oak to the Emancipation Oak, from wine and whisky barrels to tall ships to the roof of Notre Dame, from King John to Shakespeare to Leonardo da Vinci, oaks have been inextricably entwined with the human experience. Join docent Paul Eldrenkamp as we learn more about the cultural history of oaks and explore what it is that makes them so useful, so distinct — and so essential.

                  Canceled Explorers Garden Tour

                  The Explorers Garden rests in a microclimate just below the summit of Bussey Hill. This nearly five-acre site provides ideal growing conditions for many species that have been challenging to grow in less protected areas of the Arboretum. As such, it has proven to be a perfect testing ground for plants collected in the expeditions of E. H. Wilson in the early 1900s to the NACPEC  (North America-China Plant Exploration Consortium) expeditions of our own time. Join docent Marie Herbert for a guided tour to learn more about some of the plants showcased in this special collection and to hear stories of the plant exploration expeditions that brought them to the Arboretum.
