Bring your enthusiasm for the natural world and leave with a creative nature journal, inspired by the trees of the Arnold Arboretum. Nature journaling is all about expressing your curiosity and wonder through sketching, calligraphy, writing, or other forms of art-making. Tap into your creativity and let yourself be surprised by the diversity of forms on display in the winter landscape.
The birds that populate the Arnold Arboretum rarely have to go far to find water. In the deserts of Botswana, Namibia, and South Africa, it's a different story, and the sandgrouse that lives in these arid environments has developed a fascinating adaptation to stay hydrated: these birds have a unique ability to absorb and hold water inside of their feathers. But how do their feathers hold water so efficiently? Dr. Lorna Gibson, Professor of Materials Science and Engineering at MIT, has found the answer. Join Dr. Gibson for a lecture to learn about these fascinating birds and the science behind them.
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.
With mating season just getting started, February is one of the best times to see signs of the Arboretum's resident coyote population. Join Horticulturist and wildlife enthusiast Brendan Keegan to look for coyote tracks and scat, check our trail cameras, and find out why all these coyotes are in Boston in the first place.
The Arboretum becomes a riot of color in October, 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.
Join docent Paul Eldrenkamp for a visit to five groups of trees that each played a particularly significant role in shaping five very different civilizations: Eastern White Pine, Cedar of Lebanon, Western Red Cedar, Oaks, and the five sacred trees of the Kiso Forest in Japan.
As we approach the end of the growing season, it’s time to start thinking about next year’s plantings! What trees or shrubs should you plant in your own yard? Which plants will fare best in your particular space and microclimate? Join Horticulturist Rowan Payne-Meyer for a class on garden design for woody plants. We will begin in the Hunnewell Lecture Hall for a discussion on garden design techniques, and then move outdoors to see the design strategies used in the Leventritt Shrub and Vine Garden and the Bradley Rosaceous Collection.
Smithsonian Trees of North America is a new, beautifully illustrated guide to more than 325 common trees on this continent. Join author John Kress for a book talk on this indispensable new guide, complete with hundreds of range maps illustrating where the trees can be found; thousands of photographs of the trees’ leaves, bark, flowers, and fruit; in-depth studies of the trees’ biology, ecology, and evolution; and fascinating discussions of the trees’ future in a world of rapid environmental change. And keep an eye out for several photos taken by our very own Ned Friedman!
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.
This is a virtual talk held over Zoom.
We know that trees are a key ally in the fight against climate change and urban heat islands, but not every tree works in every situation. Selecting the right tree for your yard or landscape is critical both for the health of the tree and for the strength of the ecosystem services they provide. Botanist and researcher Henrik Sjöman’s new book, “The Essential Tree Selection Guide,” is a valuable new tool for making these tree selection decisions: an A to Z guide of over 550 trees, the book comes complete with explanations of each tree’s ecosystem benefits, its resilience to drought and storms, and key considerations for site placement. Join us on December 8 for a virtual book talk on this invaluable new guide.
Author Henrik Sjöman is Senior Researcher at the Swedish University of Agricultural Sciences, Scientific Curator at Gothenburg Botanical Garden, and Honorary Research Associate at Kew Gardens.

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.
