The Arnold Arboretum of Harvard University is a community resource for education, offering a variety of learning opportunities including lectures, classes, workshops, and tours of our living collections and historical landscape. Join us as we explore the biology and horticulture of woody plants, and delve into topics related to Earth’s biodiversity and evolutionary history, the environment, conservation biology, and key social issues associated with current science.

The Arboretum offers a range of programming and activities, including Tree Mobs, art exhibits, guided tours, and other digital and in-person educational opportunities:
