History of Seed Savers Exchange
Seed Savers Exchange was founded in 1975 by Diane Ott Whealy and Kent Whealy, who began sharing seeds inherited from Diane's grandfather. From that small start the group built a membership network of gardeners and growers who preserve and pass on heirloom varieties.
The organization centers on Heritage Farm outside Decorah in northeast Iowa. Over the decades it has added a visitor center, trial gardens, historic orchards and heritage livestock. Iowa PBS and other outlets have featured it as the largest nongovernmental seed bank in the country.
What Seed Savers Exchange Grows and Raises
Heritage Farm covers 890 acres and grows nearly 1,000 seed varieties each year, according to the visitor page. The seed collection is stored on site. Grown plants are evaluated, regenerated and offered to gardeners and farmers.
The grounds include the Historic Orchard with hundreds of apple varieties and the Amy Goldman Heritage Orchard with Midwestern apples. Ancient White Park cattle, a rare heritage breed, graze the property. Trails, gardens and trout streams are open to visitors from sunrise to sunset year-round, and a visitor center runs set hours.

Somewhere on the Decorah hills, a Mortgage Lifter tomato is quietly doing more for Iowa's food history than most of us manage before breakfast. We at farm.FM dabble in farm satire, farm humor, ranch humor and farm jokes, and an 890-acre seed vault with rare white cattle gives us gentle material about peas, pedigree and patience. We promise to be as careful with our puns as the staff are with their seed envelopes.
For context, farm.FM is the nation's first satirical farm site and the home of Tractor Tunes, country music for farmers. Its contributors each keep an archive, and this one is a good sampler of ranch humor and farm jokes.
