The Cosmic Tree: A Universal Symbol of Life: Ginkgoes & Conifers
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.
Research Spotlight: Climate Change and Root Exudates
Climate change is impacting every part of the plants at the Arboretum, from the buds down to the roots. Join researcher Nikhil Chari to learn how elevated temperatures and carbon dioxide are impacting tree roots, and the carbon they send back out into the soil. Nikhil will demonstrate how he takes root samples and soil cores, discuss his research on carbon cycling, and compare the root morphology of different plants in the landscape.

Mushroom Hunt
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.
Tree Mob: The Oldest Tree in the Arboretum
Long before this landscape had ever dreamed of becoming an Arboretum, a white oak grew quietly on the slopes of Peters Hill. Years passed and Arboretum staff eventually incorporated this very old tree into our official collections, making it possibly the oldest accessioned tree in the landscape. Join Assistant Curator Miles Sax for a Tree Mob to learn about this oak, what the landscape looked like before it was an Arboretum, the science of tree age, and how the Arboretum manages those trees that we never chose to plant but which are a treasured part of our collections nonetheless.
Built to Withstand: How Plants Resist Wind and Weight
How do trees, bamboo, marsh grass stems and cattail leaves stand so tall? Join Materials Science Professor Lorna Gibson for a fascinating talk exploring how the internal structure of plants gives them remarkable strength and stability—allowing them to withstand howling winds and even support their own massive weight.
Owl Observations
Dusk is a perfect time to look and listen for Great Horned Owls, often heard calling throughout the Arboretum’s collections. Join Arboretum Horticulturist Brendan Keegan and Matt Kamm, Associate Director of Field Conservation at Zoo New England, to hear about the owls’ breeding and nesting behavior, learn how to go owling ethically, and possibly hear and see a few owls as well.
Little Explorers
Join us at the Arboretum as we read and discover new things about the natural world. During this one-hour program for our youngest guests and their grownups, we will read a nature inspired story, do a craft, and go for a nature walk to continue exploring the theme. The weekly themes are inspired by what is happening seasonally at the Arboretum.
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.
Reading the Forested Landscape
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 on Hemlock Hill: learn about forest species structures, succession dynamics, and how the topography of the earth itself affects the species living there.

This online event will feature Arnold Arboretum Director William (Ned) Friedman, Chief Scientist at the China National Botanical Garden (North Garden) Jinshuang Ma, Professor of Sociology at Beijing Normal University Hu Xiaojiang (granddaughter of Hu Xiansu), and other speakers discussing Hu’s life and influence.
Conservation in a Changing World
Part of the mission of the Arnold Arboretum is stewardship of the earth’s botanical diversity and its essential value to humankind. This one hour tour through the landscape, led by docent Vicki Amalfitano, will highlight important Arboretum historical conservation efforts that have preserved distinct native and exotic species, and current efforts in our living collections to mitigate habitat disruption and climate impact. Learn about plant expeditions to preserve species in the face of climate change and new pathogens, research initiatives, as well as the Arboretum’s green initiatives and local collaborations to improve our urban canopy.
Young Friends of the Arnold Arboretum
This event for the Young Friends of the Arnold Arboretum features an enchanting evening of food, drinks, live music, and content tables in our Weld Hill Research Building —a state-of-the-art facility that is typically closed to the visiting public. Designed to appeal to those 21-45 or who are young at heart, this event is a premier opportunity to immerse yourself in the plants, purpose, and passion of the Arnold Arboretum with other metropolitan nature enthusiasts. Come learn about the research that the Arboretum is doing in the face of climate change as we maintain our 281-acre “museum of trees.” Please note that this is a 21 and older event.
Canceled Barking Up the Right Tree: A Tour of Bark Diversity at the Arboretum
*This program has been cancelled* What is there to see at the Arboretum after all of the leaves have fallen and before spring flowers start to bloom? Bark! Shaggy bark, mottled bark, striped bark: the Arboretum has it all. Join Horticulturist Rachel Lawlor to see some beautiful bark highlights, learn how to identify some trees by their bark, and learn why that bark looks the way it does.
Birding at the Arboretum
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. We will cover a variety of habitats and focus on the changes that seasonal migration brings to our resident birds, so come back often to keep up with the seasons!

Flower Visitors at the Arboretum: Can Honeybees and Native Pollinators Co-Exist?
Most of us know honeybees for the delicious honey they create (and the occasional sting!). But for scientists, the non-native honeybee represents a potential threat to our native bumblebees and butterflies. Biology professor Dr. Richard Primack has been studying these insects at the Arboretum, observing flower visitors at over 600 plant species to determine if honeybees and native pollinators can co-exist. Just us for a research talk and discover the results of this years-long investigation.
Owl Observations
Dusk is a perfect time to look and listen for Great Horned Owls, often heard calling throughout the Arboretum’s collections. Join Arboretum Horticulturist Brendan Keegan and Matt Kamm, Associate Director of Field Conservation at Zoo New England, to hear about the owls’ breeding and nesting behavior, learn how to go owling ethically, and possibly hear and see a few owls as well.

Growing Plants from Hardwood Cuttings
Hardwood cuttings are one of the many techniques the Arboretum uses to propagate its plants: propagators take cuttings from the mature stems of woody plants, carefully trim and coat the ends in rooting hormone, then plant them in specially designed growing media. Join Arboretum Propagator Sarah Shank for a hands-on workshop to learn this specialized form of propagation: the class will begin with a presentation on the biology of hardwood cuttings, then head outside to collect our own cuttings from nearby woody plants, and finally return inside to prepare and root the cuttings in growing media. Participants will bring home a small tray of cuttings to grow into their own small trees and shrubs.

Winter Tree ID
Winter can feel like one of the hardest times to identify trees, with most of their characteristic leaves and flowers gone for the season. But with help from experienced horticulturist and plant science teacher Nicole Forsyth, you can start identifying common winter trees from the woods and streets of Massachusetts based only on their bark, buds, twigs, and persistent fruit. This class will begin indoors with a presentation in the lecture hall, and then move outside for some identification practice in the landscape.
