The Connecticut College Arboretum manages four major plant collections containing 6,247 individual, accessioned living plants. Origin, date of acquisition, size, location and evaluation are documented and mapped by curator on a five-year rotating basis in The Native Plant Collection with Special Collections and Gardens, the Caroline Black Garden, the Greenhouse and the Campus Landscape.
In addition to our Plant Collections, our Natural Areas are well worth a visit.
Using the College's Geographic Information Systems (GIS) Lab, we have created numerous interactive maps to help navigate through our collections. Printable self-guided tour maps are also available to plan out your visit.
The Arboretum offers programs, an annual photo contest, bulletins and publications to help foster learning of our 750 acre arboretum. Resources to promote ecological landscaping are available on our website. Come learn with us!
