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.
Black swallow-wort is a highly invasive vine in the U.S. and Canada, but in Europe it grows benignly, kept in check by a number of insect herbivores that only live in that part of the world. But what if we could bring one of those insects to New England? Could it control this highly invasive plant? Professor Lisa Tewksbury from the University of Rhode Island has released a number of Hypena opulenta moths in the Arboretum to see if it would control the black swallow-wort here, and now it’s time to return to that part of the landscape and see if the experiment has worked. Join Professor Tewksbury for a Research Spotlight to learn about her work and see if we can find evidence of Hypena opulenta larva on the black swallow-wort plants here.
Have you ever wanted to learn more about the feathered friends you see and hear on a walk through the Arnold Arboretum? If so, please join birders and volunteers TJ and Allison for a leisurely 90-minute bird watching walk.
Mountain laurels are as fascinating as the are beautiful, with stamens that catapult pollen onto their pollinators and wood that is so easy to carve that it was nicknamed “spoonwood.” Join Horticulturist Brendan Keegan for a walk to learn about the botany, ecology, and cultural significance of these beautiful flowers at peak bloom.

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.
*Rescheduled from May 30 due to weather.* 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. Join Manager of Adult Programming and Events Sarah Nechamen for a walk to learn about these poisonous plants, the chemicals they contain, and the strange histories they carry with them.
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.).
As the Arboretum’s hydrangea collection begins to bloom in shades of blue, white, pink, and purple, stop in the Hunnewell Lecture Hall for a book talk on ‘Hydrangea Happiness: Planting, Pruning, and Blooming.’ This beautifully illustrated guide by author C.L. Fornari is a boon for beginner gardeners and experienced horticulturists alike. Learn about the most popular hydrangea varieties, how to manage planting and ongoing maintenance, and surprising myths and misinformation about these beautiful shrubs.

Arboretum members are invited to a special dedication event honoring Hu Xiansu (H. H. Hu), a scholar regarded as the father of modern botany in China. Join us for the unveiling of a memorial plaque beneath one of our original dawn redwood (Metasquoia glyptostroboides) trees, grown from seed Hu shipped to the Arnold Arboretum in 1948 shortly after the discovery of this “living fossil” in isolated groves in southeastern China. The memorial recognizes Hu’s central role in identifying and introducing the dawn redwood to the world and commemorates the centenary of his receiving a doctorate in biology from Harvard. The dedication will take place on Friday, June 26 at 2:30pm beneath dawn redwood 524-48*AA, located near the front of the Hunnewell Building at the Arborway Gate entrance. We hope you can drop by for this brief gathering to celebrate Hu’s remarkable work and enduring legacy.
Even after most of the spring flowers have closed up, the plants of the Arboretum are bursting with bizarre odors and enticing aromas– if you know where to look. Join Head Arborist John DelRosso for a “Scratch ‘n’ Sniff” tour of the Arboretum and discover aromatic leaves, bark, and of course, flowers.
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.
The Bradley Rosaceous Collection has beautiful roses on display in a stunning rainbow of colors–but roses are not the only thing you will find in this garden. There are many other plants in the rose family, from crabapples and cherries to hawthorn and medlar. Join Horticulturist Rachel Lawlor for a tour of the Bradley Rosaceous Collection and learn about the wide variety of Rosaceae species, the susceptibility of this family to pests and disease, how the Arboretum is handling these challenges, and how this unique garden came to be.

Hundreds of mushrooms hide beneath the Arboretum’s canopies, silently blossoming into unique forms then withering away again just as quickly. Join local mushroom enthusiast Maria Pinto to search for these fascinating organisms on the Arboretum grounds, both edible and poisonous alike. Along the way you will learn what mushrooms to look for in different habitats and seasons, how they move through ecosystems, and what the Arboretum’s unique collections affect what mushrooms you might find here.
*Rescheduled from July 11* The forest is a constantly changing landscape where tree species dominate and then fade away, to be replaced by other species in the ongoing process of succession. Join Horticulturist Brendan Keegan to see these dynamics at play in Bussey Brook Meadow: learn what species are found in an urban wild like this, how the landscape is used to study spontaneous vegetation, and explore the interplay of native, exotic, and invasive species in this unique corner of the Arboretum.

From increased cerebral blood flow to stronger immune defenses, come discover for yourself what happens when we unplug, slow down and open our senses to notice more of our natural surroundings. All the prompts, invitations, sharing and ways of participating are optional and open to interpretation.
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.
