Scott Arboretum

Scott Arboretum. An arboretum and public garden encompassing the entire 425-acre campus of Swarthmore College in Swarthmore, Pennsylvania. Established in 1929, it serves as a living museum of woody plants and horticultural display, integrating botanical collections with the college's educational mission. The arboretum is named for Arthur Hoyt Scott, a 1895 graduate of the college, whose family endowment provided for its creation and ongoing development.

History

The arboretum was founded in 1929 following a bequest from the family of Arthur Hoyt Scott, who had a deep interest in horticulture and the campus landscape. Early development was significantly guided by the college's first director of grounds, John W. Nystrom, who began systematically planting trees and shaping the landscape. A major period of growth occurred under the long tenure of horticulturist and educator J. Franklin Styer, who expanded the collections and their educational use. Throughout the 20th century, the arboretum evolved from a campus beautification project into a professionally curated collection, with notable contributions from landscape architects like John Caspar Wister and subsequent directors who have emphasized botanical diversity and conservation.

Collections

The arboretum's living collections include over 5,000 kinds of ornamental plants, with particular strength in woody species adapted to the Mid-Atlantic states region. It holds significant collections of cherry, magnolia, holly, viburnum, and oak, many of which are part of official Plant Collections Network collaborations. The Hydrangea collection and the Conifer collection are nationally recognized, with specimens gathered from plant exploration expeditions across Asia and North America. These curated collections serve as genetic repositories and are used for research on climate adaptability, pest resistance, and horticultural performance by institutions like the Morris Arboretum and the United States Department of Agriculture.

Gardens and features

The campus is organized into a series of thematic gardens and naturalistic landscapes. The Terry Shane Teaching Garden serves as a primary display area for seasonal plantings and demonstration beds. The Nason Garden and the Harry Wood Garden offer more intimate, formally designed spaces. Notable features include the Pinetum, the Crum Woods—a preserved native forest—and the Dean Bond Rose Garden. The Amphitheater, designed by Thomas W. Sears, and the Scott Horticultural Center are central architectural landmarks. Other highlights are the Winter Garden, planned for year-round interest, and the Cherry Border, which creates a dramatic spring display along Magill Walk.

Public engagement and education

The arboretum conducts an extensive program of workshops, lectures, and tours for the general public, horticultural professionals, and the Swarthmore College community. It hosts major annual events like the Plant Sale and the Garden Day symposium, often featuring speakers from institutions such as Chanticleer Garden and Longwood Gardens. Educational outreach includes internships, the Arboretum Associates membership program, and collaborative projects with the Pennsylvania Horticultural Society. These programs emphasize sustainable gardening practices, botanical art, and the importance of plant diversity, extending the arboretum's influence beyond the campus.

Governance and support

The arboretum is an integral department of Swarthmore College, governed by the college's administration and advised by a committee of faculty, staff, and community members. Financial support comes from the original Scott Family endowment, annual gifts from the Arboretum Associates, and grants from organizations like the Institute of Museum and Library Services. Operational management falls under a director who oversees horticulture, curation, and education staff. This structure ensures the arboretum fulfills its dual mission as a vital resource for the college's academic programs in biology and environmental studies and as a public garden for the Delaware Valley region.
