Sources of Organic and Untreated Non-GMO Seeds


Organic farmers are required by USDA-NOP regulations to use organic seeds and planting stock when commercially available. They can use non-organic, untreated seeds when organic seeds are not available in the form, quality, or quantity they need. Annual seedlings must be organic; only the USDA Secretary can grant a variance for seedlings. Perennials can be started from non-organic stock, but must be raised organically for one year before any crop is harvested as organic. Seeds, seedlings, and planting stock that have been treated with prohibited substances are allowed only if required by federal or state phytosanitary regulations. Organic sprouts can only be produced using organic seed. In no case are genetically engineered seed varieties allowed. (See 7CFR 205.105(e) and 205.204 for exact regulatory text.) Growers in the southern states have limited regional organic seed sources. Most of them buy seed from other states.

Regional Seed Resources

The Save Our Seed Project is a unique regional resource created in response to the limited availability of organic and open-pollinated heirloom seed. Save our Seed is working to increase the availability of regionally adapted, open-pollinated, certified organic seed and to develop a southern seed network.

This project has published a series of seed production manuals: The Bean Seed Production Manual; The Tomato Seed Production Manual; The Isolation Distance Guide; The Seed Processing and Storage Manual, and the Organic Brassica Seed Production Guide. Each guide provides details for production of organic seeds in the Southeast. Save our Seed also maintains a current database of more than 100 organic seed sources and assists growers in determining whether the seeds they seek are commercially available.

The Southern Seed Legacy, a membership association, was developed to recover, save, and increase the diversity of heirloom plants and traditional knowledge of the American South. More than 400 varieties of heirloom seeds, with photos, are posted on their Web site, %7Eebl/southernheirloom; email:

The Seedsaving and Seedsavers’ Resources Web page provides manylinks to sources for heirloom and non-GE seeds, information and resources for saving seeds, and seed exchange networks. Links are from the U.S., several European countries, the U.K., and

The ATTRA publication Suppliers of Seed for Certified Organic Production has been updated and is now in the form of a searchable on-line database. The database provides sources for organic seed for agronomic and horticultural crops. Some national mail-order suppliers of untreated seed are included, with emphasis on small, alternative seed companies offering open-pollinated vegetable, flower, and herb seed. Farmers can contact their certifying agents or state departments of agriculture to find out whether these agencies can supply lists of organic seed sources.

The Organic Materials Review Institute (OMRI) lists some sources of organic seed. For grain growers interested in using local, bin-run organic seed, see the ATTRA publication Marketing Organic Grains for a regionally balanced list. The ATTRA publication Seed Production and Variety Development for Organic Systems discusses additional seed sources. The buyer needs to ask to see the seed supplier’s documentation, including organic certification.

Companies Selling Organic Seeds: Source List

The Southern Organic Resource Guide does not endorse any seed companies, but we have made an effort to compile a comprehensive listing of organic seed sources to assist organic producers. Organic farmers in the South provided most of the listings. Inclusion or omission on this list is neither a statement of endorsement nor an implied criticism. Growers are encouraged to visit listed Web sites; many include extensive seed supplier lists. Companies are listed in alphabetical order.
