. . . to save North America's diverse, but endangered, garden heritage for future generations by building a network of people committed to collecting, conserving and sharing heirloom seeds and plants, while educating people about the value of genetic and cultural diversity.Located on the 890-acre Heritage Farm in Decorah, Iowa, SSE is open to visitors from April to October, and sponsors special events such as seed starting, grafting, and gardening workshops. It also hosts an annual conference and campout. To learn more about Seed Savers Exchange and the benefits of membership, visit its website.
