The Connecticut College Arboretum is a sprawling natural sanctuary for discovery and relaxation. This 750-acre botanical garden and arboretum, nestled on the campus of Connecticut College, offers a free and accessible connection to the natural world, fostering both education and tranquility. Open daily from sunrise to sunset, it invites visitors year-round to explore its diverse landscapes, from cultivated gardens to pristine natural areas, making it a unique ecological classroom and recreational haven.
The Arboretum is comprised of several distinct and captivating collections. The 25-acre Native Plant Collection showcases trees, shrubs, and woody vines indigenous to eastern North America, featuring highlights like the Nancy Moss Fine Native Azalea Garden with its 15 species of azaleas, the Josephine Hooker Shain Mountain Laurel Garden (celebrating Connecticut's state flower), and the Lincoln and Lillian Dauby Gries Conifer Collection. The Caroline Black Garden, an ornamental haven, displays a mature array of trees and shrubs from around the world, complete with a charming stream and pool. Additionally, the College Campus itself serves as a living collection, boasting a variety of specimen trees from across the globe, including the rare Franklin tree (extinct in the wild) and magnificent tulip trees, alongside scenic views of the Thames River and Long Island Sound.
Visiting the Connecticut College Arboretum is an experience that constantly evolves with the seasons, promising something new with each return. Whether you're marveling at the spring blooms of azaleas and wildflowers, enjoying Shakespeare by the pond in summer, or basking in the spectacular autumn foliage, its dynamic beauty is truly memorable. It’s a place for quiet contemplation, vigorous exploration on its varied trails, or engaging with nature through its educational programs and community events, offering a profound appreciation for ecological diversity and conservation.

The Connecticut College Arboretum was established in 1931, initially encompassing about 60 acres, with a mission to serve both Connecticut College and the wider community. Over the decades, it has expanded significantly to its current 750 acres, becoming a vital center for research, teaching, and public education in ecological and environmental studies. Notable early developments include the establishment of the Caroline Black Garden in 1928, named after the college's first botany department chair, and the continuous beautification efforts on the college campus, which began as early as 1911 with the planting of unusual species. While early campus plantings included diverse global species, the Arboretum's core focus has consistently been on the study and preservation of native New England flora.
