    • Grapevines of the Leventritt

      The Leventritt Shrub and Vine Garden contains over a dozen grapevines, many of which have rich histories in plant breeding and winemaking. Join winemaker and author J. Stephen Casscles for a walk through Leventritt and explore these diverse grape species, their long histories in grape breeding, and their contributions to sustainable agriculture. The group will gather in front of the Hunnewell Building and then walk the 10 minutes to the Leventritt Garden.

            Tai chi is a Chinese martial art known for its slow, intentional movements which act as a form of moving meditation for practitioners. Join International Tai Chi Gold Medalist and referee Hongsheng Jin for this one-hour tai chi class, appropriate for beginners and experienced students alike. The class will begin with breathwork and stretching, continue with a moving meditation and a walk practice, and conclude with a formal tai chi practice.

                Plankton Painting

                In this experimental photography workshop led by local artist and scientist Jess Holz, participants create ‘paintings’ using microscopic plankton collected from the Arboretum’s ponds. Participants use a microscope in combination with software which creates video akin to timelapse photography- acting at the decisive moment, participants snap photos of the trails created by these microscopic creatures. Participants will learn basic identification of microscopic pond life while getting a fascinating glimpse into their dynamic behavior, such as the helical paths of flagellates and the water currents generated by rotifers as they feed.

This walk will be fast-paced, energetic, and will involve walking over hills and rough terrain. Note that this is not a traditional tour: you may hear some information about individual trees and history, but the main goal is to get outside and get some exercise!

Join us for a Research Spotlight program to learn about Michael’s research and search for some of these caterpillars in the landscape.

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

                      Cosmologies are ways of understanding the nature of the universe, of experiencing the world in all its variations including the visible and the invisible. Over millennia trees have served as the mythological archetype of the world’s axis (axis mundi), the pole through the earth’s center which connects the worlds above and below. Within a cosmic-magical model of the world  (imago mundi), trees also evolved in various cultures to possess innate spiritual powers or as conduits for communication with the holy or sacred.

                      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?

                        Hidden among the beautiful flowers and innocent-looking shrubs of the Arboretum are some of the world’s most sinister poisons. White snakeroot, yew and even the beloved rhododendron are all filled to the brim with toxins that have both enticed and tormented people for generations.

                                    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.

                                      The towering Eastern White Pine once dominated New England forests and served as an important symbol for Indigenous peoples, but the British Royal Navy’s thirst for tall, straight, trees to use as ship masts eventually led to the destruction of the vast majority of old growth pines in Massachusetts. Join Gwyneth Shanks and AB Brown for a performance piece highlighting Pinus strobus’s dramatic colonial history in which American settlers fought back against King George’s large-scale destruction of their forests, leading to direct resistance, riots, and eventually to the Boston Tea Party itself.

                                                    The old-growth forests of Oregon and Washington play a vital role in the ecosystems there, supporting a wide diversity of life and sequestering carbon in enormous, long-living trees. The east coast, by contrast, has been logged and clear cut for generations and has precious little old-growth forest left. Join environmental journalist and Bullard Fellow at Harvard Forest, Lynda Mapes, for a talk about her book “The Trees are Speaking: Dispatches from the Salmon Forests.” In this thought-provoking new book, Mapes interviews scientists, loggers, and Indigenous activists to answer deep questions about the importance of old-growth forests, the conflicting desires around how to manage them, and how we can protect these forests into the future.

                                                                        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.

                                                                          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.
