To collect and make available for research use unique, high quality images of and documentation relating to a wide variety of cultivated gardens throughout the United States that are not documented elsewhere since historic, designed and cultural landscapes are subject to change, loss and destruction.

In this way, AAG strives to preserve and highlight a meaningful compendium of significant aspects of gardening in the United States for the benefit of researchers and the public today and in the future.

The Garden Club of America Collection, which was donated in 1992, includes documentation of landscape architects such as Marian Coffin, Lawrence Halprin, Beatrix Farrand, Hare & Hare, Gertrude Jekyll, Umberto Innocenti, Jens Jensen, Charles Platt, Ellen Biddle Shipman, and Fletcher Steele.

[2] Much of their importance lies in the documenting of many gardens that no longer exist or have fallen into disrepair.

[6] "Community of Gardens" is a website and a free mobile app where people can view some of the digital archives of AAG and share their own personal stories, photos, videos, and audio of gardens around the world.
