Seed Savers Exchange
Seed Savers Exchange, founded in 1975, is one of the largest seed libraries in North America, offering thousands of seed varieties. They aim to protect and nurture America’s diverse crop heritage by collecting, growing, and sharing heirloom and open-pollinated seeds. Seed Savers depends on participatory preservation, meaning that membership engagement is essential in the preservation of seed varieties. The vegetable planting and seed saving instructions section of the website is particularly useful.
