One of the reasons many of us grow our own food is so we know it’s grown healthfully and according to our values, and that begins with seeds. The following companies are a few (but not all) of the conscientious seed companies you can buy from—they all guarantee reliable seeds and a dedication to sustainable agriculture and educational outreach. In addition, they’re committed to thoughtful customer service, environmental stewardship and employee welfare.

The 700-plus heirloom, open-pollinated, organic and untreated seeds offered by Southern Exposure Seed Exchange are all selected for good performance on the company’s 72-acre certified organic farm. To further genetic diversity in our food supply, in addition to many popular heirloom food plants, Southern Exposure specializes in rare heirlooms and unusual food crops that came to the U.S. with immigrants, such as Southern peas and peanuts, naturally colored
cotton, and corn varieties for roasting and cornmeal.

Notable Customer Service: Here’s a comment from a gardening website not affiliated with Southern Exposure: “Talking to them on the phone is like talking to your mama. They’re warm, they care.” The Southern Exposure team uses this comment as its official inspiration for every customer interaction, whether by phone or email.

Education and Events: It’s hard to find a more picturesque location for an annual educational event than that sponsored by Southern Exposure—the Heritage Harvest Festival held each September at Thomas Jefferson’s Monticello. And in an effort to build a more sustainable food system in the Midatlantic and Southeast regions of the U.S., Southern Exposure works cooperatively with numerous nonprofits to offer seed-saving education and resources for home gardening and small-scale agriculture all over these regions. The group also works with school gardens and homeschoolers to help their children learn to grow their own seeds.

Environmental Commitment: The company aims to be a resource base that can continue indefinitely, so its employees attempt to further an agriculture system that values soil conservation and integrated pest management. The employees live and work cooperatively, and they build their own buildings with smart, sustainable techniques such as passive solar construction, living roofs and water reclamation. They also support regional organizations that work for a sustainable future.

Social Responsibility: Southern Exposure is a worker-owned and managed cooperative that believes everyone has a right to save seed. The company promotes this and other core values through programs such as Plant a Row For the Hungry, donating thousands of seed packets to schools and community organizations each year, and donating seeds, money and information to Seed Programs International, which works to reduce world hunger by empowering people to grow their own food. Southern Exposure also operates a farming internship program to keep the local food movement growing.
