For many of us, botanical gardens and arboretums are beautiful places to visit and serve as peaceful settings for relaxation, family time, or recreation. The gardens and arboretums on this list, however, serve a higher purpose. Not only do they beautify their campuses and communities, they also serve as environmental stewards, outdoor classrooms, and living laboratories. These university botanical gardens and arboretums add value to the college experience by offering hands-on learning experiences and research opportunities that students won’t find anywhere else.
The best of these natural teaching settings have close connections with university programs and degree paths in agriculture, plant science, and environmental studies. They also have strong community outreach programs and allow students to participate in volunteer programs, service learning projects, and internships. These opportunities allow students to get their hands dirty and acquire the training and networking experiences they need to be successful in their chosen career paths. In evaluating the top university botanical gardens and arboretums, our editors looked for schools that not only maintained a manicured landscape, but also made the most out of their facilities’ resources by bringing the learning outdoors and turning theoretical concepts into real-world experiences for their students.

University of California Botanical Garden
University of California
The University of California Botanical Garden at Berkeley boasts a history almost as rich as its soil. In fact, its roots began in the 1870s when the founding Dean of Agriculture, Eugene W. Hilgard, planted its first few seedlings. Twenty years later, the garden was formally established by the chairman of the Botany Department, E.L. Greene, at which time it began to flourish. Today, the garden is the proud home of over 13,000 different flowers, shrubs, and plants from across the globe. It serves not only as a natural instructional facility for students studying plant sciences at the university, but also a beautiful learning tool for the community’s children and adults alike. The garden staff offers a variety of tours and educational programs, as well as a summer camp for kids ages 5-10.

St. John’s Abbey was settled in the mid-1800s by Benedictine monks after land treaties with the native Indian tribes opened the region to European settlers. Soon after, St. John’s College (now University) was established on their new land that they referred to as “schoenthal” or “beautiful valley.” The postglacial, 2,800-acre parcel was chosen by the monks for its diverse habitats of hardwood forest, prairies, lakes, and streams. As immigrants from Bavaria, it was monks’ vision to be good stewards of the land and transform their new settlement to the likes of their homeland. After nearly one hundred and fifty years of land management and preservation based on Benedictine principles of stability, hospitality, and stewardship, the monks designated St. John’s University’s campus and surrounding acreage a natural arboretum. Today, the arboretum serves as a place of study and research for more than 8,000 students every year.

The College also uses the arboretum as a testament to its dedication to creating a sustainable landscape with a focus on native plants.
Lovingly referred to by students and faculty alike as “The Arb,” Cowling Arboretum at Carleton College consists of 880 acres of outdoor classroom for students, especially those studying biology and geology at the school. Those in classes with a field component value the opportunity to complete class assignments and conduct research in the arboretum, which is just a short walk from campus and available anytime day or night for academic or recreational use. Employment opportunities in The Arb are also available for students during the school year and can be a source of both income and inspiration. For instance, the position of Cole Student Naturalist enables students to become Arboretum Ambassadors, educating other students about the arboretum, leading field trips, and writing for the Arb website.
