Chapman Field in Miami is a U.S. Department of Agriculture research station that began in 1898 as the federal government’s first plant introduction garden for tropical plants. Established through land donations from Mary Brickell and Henry Flagler and shaped early by David Fairchild and Herbert J. Webber, it became central to testing foreign plants for possible use by growers. After outgrowing its original Miami sites, the station moved onto part of the former Chapman Field air training ground in the 1920s and later expanded to 197 acres. It has since registered more than 20,000 plant introductions and become an important center for fruit research, quarantine work, and germplasm conservation.
