The Florentine Craftsman Collection contains trade literature and photographic images compiled by the Florentine Craftsmen firm of Long Island City, New York, dating from 1921 to 1976. Most of the manufacturers' literature--including catalogs, flyers, and brochures--deals with outdoor furniture and ornaments, iron work fixtures, and railings. Some of the materials relate specifically to product lines by Florentine Craftsmen, though most illustrate the work of other manufacturers of outdoor furnishings.

The Victorian horticultural subjects vertical file is a study file that was compiled for the Smithsonian exhibition "A Victorian Horticultural Extravaganza." Includes copies of materials from various published sources related to Victorian-era (1837-1901) garden tools and accessories, costume accessories, the decorative arts, ladies' fancy work, garden furniture and ornaments, the commerical horticulture industry, landscape design, plants, exhibitions, and garden-related publications.

The Historic Gardens Stereograph Collection includes 807 stereographs that depict various public gardens, parks, and tourist attractions throughout the United States, with an emphasis on features related to horticulture and landscape design, including plants, garden furniture, and topiaries. Most, but not all views, show exterior features. A number of stereographs indicate the photography studio on the recto or verso, as well as a series or image number. Many include a brief caption; some include a lengthy description on the verso. Few are dated.

The Horticultural subjects vertical file contains materials related to garden history, landscape architecture, garden furniture and ornaments, gardening practices and design, horticulture, conservation, plant folklore and other topics compiled from various published sources.

The American gardens collection, a component of the Archives of American Gardens (AAG), includes holdings not associated with other major collections in the archives. The slides, photographs, plans, and files in this collection come from various private donors. Individual sub-units typically depict a single garden.

This series contains 128 glass lantern slides of images photographed by Louise Newton, a founding member of the Ridgefield Garden Club, on a Garden Club of America visit to England in June 1929. It is very likely that Louise Newton was part of Group A on the trip.

The Ken Druse Garden Photography Collection contains approximately 45,000 film transparency and 35mm slide images, dating from 1978 to 2005, of gardens, garden features, and flora photographed by garden writer and photographer Ken Druse. The photographic images document numerous private and public gardens throughout the United States and a few in Canada. Many have appeared in Druse's own books and articles as well as those by other writers. Approximately half of the collection is arranged according to specific garden, the other half by garden feature. A small portion of the collection consists of slide lectures given by Druse. Some images are identified with general captions and dates. Images documenting specific gardens are sometimes accompanied by handwritten notes, garden descriptions, and articles. Annotations appearing on certain images indicate the publication in which they appeared. The collection includes 'outtakes' or bracketed images that give insight into Druse's photo shooting process.

This collection contains over 37,000 35mm slides, 3,000 glass lantern slides and garden files that may include descriptive information, photocopied articles (from journals, newspapers, or books), planting lists, correspondence, brochures, landscape plans and drawings. Garden files were compiled by Garden Club of America (GCA) members for most of the gardens included in the collection. 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. A number of the slides are copies of historic images from outside repositories including horticultural and historical societies or from horticultural books and publications. The GCA made a concerted effort in the mid-1980s to acquire these images in order to increase its documentation of American garden history. Because of copyright considerations, use of these particular images may be restricted.

The Eleanor Weller Collection dates from circa 1978-2006 and consists of documentation and research files relating to the Garden Club of America's Slide Library of Notable American Parks and Gardens (later donated to the Smithsonian Institution as the Garden Club of America Collection) and the book, The Golden Age of American Gardens: Proud Owners, Private Estates, 1890-1940, co-written by Weller, as well as thousands of photographic images of historic and contemporary gardens compiled or taken by Weller. Materials include correspondence, research notes, clippings, brochures, lecture scripts, photocopied images from archival repositories, and original and duplicate 35mm slides.

The Maida Babson Adams American Garden Collection documents the work of Molly Adams, a free-lance garden photographer who photographed hundreds of private and public gardens, many of them in the mid-Atlantic region, from the late 1950s through the mid-1990s. It includes slides, photographic prints, negatives and transparencies. A significant number of images document the work of landscape designers Nelva M. Weber, Alice Recknagel Ireys, and Friede Stege. Roughly 50 gardens do not have an identified location. Some images have captions and other information written on them.
