• Explorers Garden Tour

    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 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.

            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.

                      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.
