The Smithsonian Institution is trying to identify images of American gardens in its archives.
Actually, you may be able to help the venerable institution solve a number of garden mysteries -- or maybe it's more accurate to say, mysteries of gardens.
Its 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 Carolin, and Virginia -- as well as unidentified locations.
