The Archives of American Gardens contain more than 80,000 images of gardens — from drawings of Colonial kitchen gardens to black and white photographs of 1930s landscapes.

Unfortunately, many are unidentified. And that limits their usefulness. So they’ve posted the images on the Web in hopes that someone will recognize them and let them know the details.

They’re posted by state — California, Connecticut, Florida, Georgia, Illinois, Maine, Maryland, Massachusetts, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina, and Virginia — as well as unidentified locations.

If you know where any of the gardens were located and details about them, the  Smithsonian asks that you contact the staff by e-mail at or by phoning (202) 633-5840.
