• Wicked Plants: A Botanical Halloween

    On the afternoon of Halloween, stop by the Hunnewell Lawn to learn about the most sinister plants in the Arboretum’s collections. Armed with spiky thorns, sticky latex, and chemical warfare, these plant species defend themselves from hungry herbivores, other plants—and sometimes from humans who wander too close. Others try to poison their neighbors, practice explosive seed dispersal, or even glow under black light. Drop by for this family friendly event and experience Halloween, Arboretum-style.

            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.

              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.

              The Regal Lily and the Redemption of E.H. Wilson

              Join Keeper of the Living Collections for a story of a flower and the early 20th Century explorer who ventured to the other side of the world, away from family and modern convenience, to collect it. The regal lily (Lilium regale) was not just an object of desire but one of such value that it would underwrite one of the most significant collecting expeditions of the day. Yet, its beauty almost betrayed the collector, nearly taking both his reputation and his life.
