Links to organizations and websites that provide lists of companies selling and providing information (See below our list of organic seed companies):

– The National Sustainable Agriculture Information Service (ATTRA) has a recently updated Searchable Database of Organic Seed Suppliers produced by Katherine L. Adam (NCAT Ag. Specialist). It provides sources for organic seed of both agronomic and horticultural crops. Some national, mail-order suppliers of untreated seed are included, with the emphasis on small alternative seed companies offering open-pollinated vegetable, flower, and herb seed. See More details about this database. And be aware that certified organic buyers need to ask to view a seed supplier’s documentation, including certification credentials. NCAT has not inspected certificates of any company listed in the database or their certifiers, nor does the listing make or imply any claims about the trustworthiness or business practices of any company.

– The Seedsaving and Seedsavers’ Resources Web Page has links to sources of heirloom, organic, open pollinated & non-GE seeds and includes lots of useful information about seed purchasing, seed saving, and seed exchange networks. Also includes articles and information about the politics and policy of the seed industry, and how to choose the right sources. (International)
