  • ‘Asunder’ and the California Wildfires

    Arnold Arboretum

    The devastating wildfires in California over the past several years have left the landscape starkly and in many cases permanently changed. Billie Mandle, Photography professor at Massachusetts College of Art and Design, and Karen Haas, Curator of Photography at the MFA, come together to talk about Billie’s new photography book ‘Asunder,’ made up of stark and haunting photos of the aftermath of the 2020 Glass Fire in Northern California. They will be joined by Director of the Harvard Forest Jonathan Thompson who will share his research on how the wildfires have changed the very makeup of California forests, from mature trees to landscapes dominated by chaparral.

    Join us for this unique panel talk that mixes science and art to look at some of the most devastating natural disasters of the past decade.

  • Olmstead and the Arnold Arboretum

  • Growing Plants from Hardwood Cuttings

    Arnold Arboretum

    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.
