The Burlington Garden Club will host Jen Kettell, Radiant Leaf Consulting, on Wednesday, April 22 at 6:45 pm in the Murray Kelly Room in the Burlington Council on Aging Building, 61 Center Street in Burlington. Jen will speak on The Camel’s Garden: Drought Tolerant Plants for a Changing Climate. The program is funded in part by a grant from the Burlington Cultural Council, a local agency supported by the Mass Cultural Council, a State agency.
Jen Kettell, BCMA is a consulting arborist serving the New England area (and occasionally beyond). As the owner of Radiant Leaf Consulting, she shares her passion for horticulture through the training she provides to both homeowners and green industry professionals. She started landscaping as a teen, continuing to farming, greenhouse production, and finally the Arnold Arboretum before she began building Radiant Leaf Consulting. Today, Radiant Leaf is celebrating just over ten years as a small local business.
She has consulted for Safdie Architects and The Trustees’ public gardens, and has served as a guest lecturer for the Massachusetts Horticultural Society, the Arnold Arboretum, and the International Society of Arboriculture (ISA).
Join the Arnold Arboretum on February 1 at noon for a talk by popular Mushroom Hunt instructor Maria Pinto on her new book, Fearless, Sleepless, Deathless: What Fungi Taught Me about Nourishment, Poison, Ecology, Hidden Histories, Zombies, and Black Survival. Maria weaves together memoir, mycology, and cultural history to illuminate the deep and surprising ways fungi connect with human life. With vivid storytelling and a fiercely original voice, she explores fungi not just as biological wonders but as tools of survival, subversion, and spiritual sustenance – especially for thos living at the margins. The program takes place in Hunnewell Hall. For more information visit https://arboretum.harvard.edu/events-2/program-catalog/

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.

Long before anyone dreamed of this landscape becoming the Arnold Arboretum, a white oak grew quietly on the slope of today’s Peters Hill. Years passed and Arboretum staff eventually incorporated this very old tree into the collections, making it possibly the oldest accessioned tree in the landscape. Join Assistant Curator Miles Sax for a Tree Mob on November 15 at 10 am 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. This is a members-only event, so sign up now at https://arboretum.harvard.edu/support/
Use the freshly fallen leaves at the Arnold Arboretum to make beautiful art, just like the famed nature artist Andy Goldsworthy. This is a chance to play in the leaves and make something beautiful– even if it only lasts until the next gust of wind!

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 on May 10 at 1 pm 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. This tour will include paved roads and woodchip paths. Please wear weather-appropriate clothing and closed toe walking shoes. Tours may be canceled in cases of the following weather conditions: severe wind, snow, ice, thunder or lightning events; temperatures over 90 degrees; temperatures below 20 degrees; or other weather events at the discretion of Arboretum staff. In the case of cancellation, you will be contacted by Arboretum staff no later than 2 hours before the start of the event. If you have questions about the status of a program, please email or call the Visitor Center at (617) 384-5209 between 10:00am and 4:00pm. Free but register at www.arboretum.harvard.edu.
