Our Commitment to Seed Preservation and Agricultural Heritage
The Philosophy Behind Seed Heritage Preservation
Seed Heritage exists to reconnect people with the fundamental practice of saving seeds—an activity that defined human civilization for 10,000 years until the last century disrupted this ancient relationship. The 1970 Plant Variety Protection Act and subsequent intellectual property expansions transformed seeds from commons into commodities, concentrating control in fewer hands each decade. By 2018, just four corporations controlled over 60% of the global seed market. This consolidation has practical consequences: varieties are selected for industrial agriculture's needs—uniformity, machine harvestability, shipping durability—rather than flavor, nutrition, or adaptation to diverse growing conditions.
We believe seed saving represents both resistance and resilience. Every gardener who saves seeds participates in decentralized plant breeding, adapting varieties to local conditions while maintaining genetic diversity that commercial agriculture abandons. The Irish Potato Famine killed one million people and forced another million to emigrate because an entire nation depended on a single potato variety. Modern agriculture repeats this vulnerability at global scale. The UN's State of the World's Biodiversity for Food and Agriculture 2019 report documented that 75% of crop diversity was lost during the twentieth century. Each lost variety represents genetic solutions to problems we haven't yet encountered.
Our approach emphasizes living preservation over static storage. While seed banks serve crucial backup functions, seeds stored in vaults don't adapt to changing conditions. Seeds grown in diverse gardens across varied climates continue evolving, developing resistance to emerging diseases and tolerance for shifting weather patterns. This distributed preservation model also embeds knowledge in communities rather than institutions. When you understand how to save tomato seeds, you possess practical skills that transcend economic systems and supply chains. The main page of our site explores these preservation techniques in detail, while our FAQ section addresses specific questions from those beginning their seed saving journey.
We recognize that seed heritage extends beyond genetics into culture and identity. The Haudenosaunee people maintain their Three Sisters planting method—corn, beans, and squash grown together—not merely as agricultural technique but as spiritual practice encoded in specific varieties developed for this purpose. Mexican communities preserve hundreds of regional maize varieties, each adapted to specific elevations, soil types, and culinary traditions. When these varieties disappear, we lose more than germplasm; we lose accumulated wisdom about how humans can live sustainably in particular places.
Building a Seed Saving Community Network
Effective seed preservation requires community rather than individual effort. A single gardener might maintain 10-20 varieties with attention to proper population sizes and isolation distances. A network of 50 gardeners can preserve 500 varieties while sharing labor, knowledge, and genetic material. Seed libraries have emerged as community infrastructure for this purpose, with over 500 now operating in North America. Richmond Grows Seed Lending Library in California, established in 2010, pioneered the model: members check out seeds in spring and return seeds from their harvest in fall, creating a revolving collection adapted to local conditions.
Regional seed exchanges serve similar functions through different structures. The Southern Exposure Seed Exchange in Virginia has operated since 1982, focusing on varieties suited to Mid-Atlantic and Southern growing conditions. Their catalog includes detailed growing information specific to the region's hot, humid summers and variable winters. This regional focus produces better outcomes than generic national catalogs because varieties are tested under conditions matching where customers garden. The Hudson Valley Seed Company in New York similarly emphasizes varieties proven in northeastern gardens, documenting performance data across multiple seasons.
Online communities complement local networks by connecting seed savers across geographical distances. The Seed Savers Exchange yearbook, published annually since 1975, lists thousands of varieties available through member-to-member exchange, with detailed descriptions written by the gardeners who grow them. These descriptions include information rarely found in commercial catalogs: how varieties perform in specific microclimates, flavor comparisons, disease observations, and cultural history. Digital platforms like GardenWeb forums and specialized Facebook groups enable rapid knowledge sharing, with experienced seed savers mentoring beginners through real-time problem solving.
We encourage participation in these networks rather than isolated practice. Seed saving knowledge transfers most effectively through hands-on demonstration and seasonal mentorship. Regional groups often organize seed swaps in late winter, where gardeners trade seeds and share growing notes from the previous season. These gatherings build relationships that extend through the growing season, creating support systems for troubleshooting challenges. Many groups also organize seed processing workshops where members learn fermentation techniques for tomatoes, winnowing methods for grains, or hand pollination for squash. The collective knowledge in these communities exceeds what any individual can develop alone.

The Future of Heritage Seeds and Food Security
Climate change makes heritage seed preservation increasingly urgent. As temperature zones shift and weather patterns become less predictable, the genetic diversity within heirloom collections provides adaptive capacity that uniform commercial varieties lack. Research from the University of Wisconsin documented that heirloom tomato varieties showed 30-40% less yield decline under drought stress compared to commercial hybrids, likely due to deeper genetic diversity allowing some plants within a population to tolerate stress better. This variation, considered a deficiency in industrial agriculture, becomes an asset under unstable conditions.
The economic model of seed saving also addresses food security differently than industrial agriculture. When communities control their seed supply, they reduce dependence on external inputs and corporate supply chains. During the 2020 pandemic, seed companies experienced unprecedented demand, with many suspending sales by April as inventory depleted. Gardeners with established seed saving practices continued planting without interruption. This resilience scales: regions with strong seed saving cultures maintain food production capacity regardless of economic disruptions or supply chain failures.
We face a critical knowledge transfer challenge. The generation that maintained traditional seed saving practices through the mid-twentieth century is passing, and many younger farmers and gardeners never learned these skills. Agricultural education shifted toward industrial methods, and seed saving largely disappeared from university curricula. Organizations like the Organic Seed Alliance work to reverse this trend through training programs and research, but the scale remains insufficient. We need thousands of skilled seed savers to maintain the diversity currently at risk. Every person who learns these practices and teaches others multiplies preservation capacity.
The legal landscape around seed saving continues evolving, with implications for heritage preservation. While saving seeds from open-pollinated varieties remains legal, utility patents on genetically modified organisms and some conventionally bred varieties create restrictions. The 2013 Supreme Court decision in Bowman v. Monsanto upheld patent protections that prevent saving patented seeds. This makes distinguishing between open-pollinated heritage varieties and patented varieties increasingly important. We advocate for seed sovereignty—the right of farmers and gardeners to save, replant, and share seeds—as fundamental to food security and agricultural sustainability. Supporting heritage seed preservation through growing, saving, and sharing open-pollinated varieties strengthens this commons against ongoing enclosure.
