Salisbury University’s arboretum spans fifty hectares, or one hundred twenty-five acres, across the campus in Salisbury, Maryland. Its collection began in 1985, and by 1988 the entire campus had been recognized as an arboretum by the American Association of Botanical Gardens and Arboreta. In May 2025 it was named for alumna Glenda Chatham Clarke and is also known by her name. The arboretum now includes more than two thousand plant species, with indigenous and exotic additions made each year. Its Delmarva Peninsula climate supports mild-temperate plants, and the grounds are also distinguished by a notable sculpture collection, including works by Augustus Saint-Gaudens, Auguste Rodin, and Jim Hill.
