• 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.

      Ask a Horticulturist – Lilacs

      Stop by the lilac collection to chat with the Horticulturist who manages the Arboretum’s beautiful lilac shrubs. Horticulturist Conor Guidarelli will be there from 2:00pm to 4:00pm answering questions about caring for lilacs, the Arboretum’s lilac collection, and what it’s like to be a horticulturist here. No registration is required, just stop by!

        The Cosmic Tree: A Universal Symbol of Life: Flowering Trees

        During this tour we will discuss angiosperms, the largest and most diverse group in the plant kingdom. All flowering trees are angiosperms, but not all angiosperms reproduce in the same way, so you may not see blooms and flowers but plenty of leaves. 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 Center Street Gate starting at Jack Dawson’s shagbark hickory (1883) then head up Oak Path to Beech Path ending at Bussey Hill Road after visiting the ash trees of Norse mythology (Yggdrasil.).

          Conifer Collection Tour

          The conifer collection at the Arnold Arboretum is a magical place to visit at any time of the year, as it is especially rich in history and diversity. Docent Cristina Squeff will lead participants through this collection explaining key identification features and sharing relevant stories about individual trees.

            “When Trees Testify” by Beronda Montgomery

            Join plant biologist and author Beronda Montgomery for a discussion of her new book, “When Trees Testify: Science, Wisdom, History, and America’s Black Botanical Legacy.” Montgomery explores the way that eight trees and shrubs testify to the experience of black Americans, from sycamores that acted as landmarks for those trying to escape slavery, to pecan propagation spearheaded by an enslaved African woman, to the traditional medicinal uses of willow bark in black communities. Montgomery takes us through black American history with trees and shrubs as our guides.

                      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.

                                  Trees have long played an important role in cultures around the world. On this tour, we delve into the ethnobotany of trees – how people of different cultures and regions made use of woody plants for food, medicine, everyday wooden objects, dyes, fibers, oils, resins, gums, soaps, waxes, tannins.  Join docent Vicki Amalfitano to explore how groups from many regions and traditions have historically used bark, roots, and leaves from native and exotic trees we have growing at the Arnold Arboretum for a variety of uses.
