• Canceled Charles Sprague Sargent and the American Landscape

    Many are aware of Charles Sprague Sargent’s role as first director of the Arnold Arboretum, establishing it as the world-renowned institution it is today. Far fewer are familiar with how his close relationships and prolific correspondence with figures of national and international prominence in the developing fields of botany, horticulture, forestry, and wilderness preservation or his leadership of seminal public sector projects such as his path-breaking survey of United States forests for the 1880 US Census shaped the American landscape far beyond the Arboretum’s walls. Docent Paul Eldrenkamp will lead a tour that explores the far-reaching influence — then and now– of the Arboretum’s first director.

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.

        Rescheduled The Science of Fall Leaf Color

        *Rescheduled from September 27 due to rain* The Arboretum becomes a riot of color in the fall with leaves turning deep red, fiery orange, and bright yellow. Have you ever wondered why this happens every autumn? Outdoor Educator Ana Maria Caballero will take us through the science of fall leaf color, including an exploration of pigments and abscission, a hands-on experiment to reveal the array of pigments present in every leaf, and a walk in the landscape to take a closer look at leaves in all phases of color change.

            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.

                      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.

                              On the afternoon of Halloween, stop by the Hunnewell Lawn to learn about the most sinister plants in the Arboretum’s collections. Armed with spiky thorns, sticky latex, and chemical warfare, these plant species defend themselves from hungry herbivores, other plants—and sometimes from humans who wander too close. Others try to poison their neighbors, practice explosive seed dispersal, or even glow under black light. Drop by for this family friendly event and experience Halloween, Arboretum-style.

The regal lily (Lilium regale) was not just an object of desire but one of such value that it would underwrite one of the most significant collecting expeditions of the day. Yet, its beauty almost betrayed the collector, nearly taking both his reputation and his life.
