The J. Horace McFarland Collection includes over 3,100 photographic images of private and public gardens throughout the United States, as well as some from foreign countries, dating from 1899 to 1963. Many of these images, generated for Mount Pleasant Press (later the J. Horace McFarland Company), were used to illustrate trade catalogs published by the firm as well as journal and newspaper articles. The collection also contains color records that were used as reference aids during the printing process, plant patents, and various publications of the McFarland Company.

This collection contains over 37,000 35mm slides, 3,000 glass lantern slides and a small number of landscape architectural plans and drawings, all of which document the history of American gardens and landscapes. Garden files were compiled by The Garden Club of America (GCA) members for most of the gardens included in the collection. These files may include information sheets, photocopied articles (from journals, newspapers, or books), planting lists, correspondence, brochures and other notes. Some gardens have been photographed over the course of several decades; others only have images from a single point in time. In addition to images of American gardens, there are glass lantern slides of the New York Flower Show (1941-1951) and trips that GCA members took to other countries, including Mexico (1937), Italy, Spain, Japan (1935), France (1936), England (1929), and Scotland.
