Seed Companies

For the past decade there has been an uproar in the vegetable seed business as Monsanto purchased Seminis in 2005, a seed conglomerate that has 40% of the U.S. vegetable seed market. More than 55 percent of store bought lettuce, 75 percent of U.S. tomatoes, and 85 percent of peppers originated through Seminis. Then, in 2008, Monsanto bought De Ruiter Seeds, one of the top vegetable breeders in the world.

Monsanto is now in the vegetable seed business for the first time, and it’s in big time. Our salad plate is now being dished out by Monsanto! We now have yet another reason to buy organic produce. Hopefully this will not go to naught, and it will be the impetus to get even more Americans to start a vegetable garden…and possibly a fruit garden as well!

In 1980, the Supreme Court ruled that genetic coding could be owned. This changed the seed industry from public to private, and corporations outside of the seed business (mostly pharmaceutical and chemical cos) started buying up seed companies. A few multinational companies now own our plants’ genes! And our choices keep getting smaller as these hybrid seed companies ‘perfect’ our seed for us, breeding out all of our food history.

Due to Monsanto’s huge purchase, you’ll need to do a bit of homework if you wish to steer clear of purchasing their seed, as even reputable seed companies that have signed the Safe Seed Pledge, are still selling Seminis (now Monsanto) seed. Buying seed from a seed exchange, buying open-pollinated and organic, are safe ways to avoid Monsanto seed.

Remember that although hybrids have been ‘naturally’ manipulated, their genes are stable. But their successive seed will be either sterile or revert back to a parent’s tendencies. Some hybrids have been around a long time and you will even see some sold as organic. Hybrids keep big seed companies in business, as you must buy the seed each year.

Genetically modified seed on the other hand, is manipulated in a laboratory. (Read more about this process in our Understanding GMO Foods post.) Many times the genes are unstable and can jump to other plants, contaminating whole fields. And since GM seed is patented, if you are found with a GM plant on your field, that you did not buy that year as fresh seed, you can be sued.

As many farmers can already attest, Monsanto has a huge budget just for investigating and prosecuting farmers for patent infringement. Monsanto is releasing new genetically modified crops—cotton and soybeans among the recent ones. If you see PVP (Plant Variety Protection) listed, that means the seed or plant carries a U.S. patent.

Another term to note when buying seed is heirloom. There is no standard as to what “heirloom” means. To a small-town seed exchange it might mean one thing, to a seed conglomerate another. Most often heirloom means that seeds are open-pollinated with at least a 50-year history. See the heirlooms wiki page for a good synopsis. Also note, before buying seed, that ‘treated’ seeds are coated in chemical anti-fungals (most likely Captan or Thiram) and dyed. Most small seed companies let you know if a seed has been treated. As to organic seed—best to buy—but most seed varieties have yet to be certified organic. We need to keep certifying varieties as organic, and this is a fairly slow process.

The first list below is a list of Safe Seed Companies—the first few listed under each region sell only organic—then those below sell some conventional seed as well, but it is noted if they sell Monsanto seed. If they do, avoid their conventional seed or check the second list, which lists Monsanto’s vegetable varieties.

The second list below is a list of popular Monsanto seed. It would be very lenghty if all were included, but there are links to Monsanto’s products pages so that you might do further research. Many seed re-sellers buy seed from a broker who has purchased a huge block of seed, the broker breaks up the order, and then re-sells to numerous mail-order seed companies. So, many companies carry the same seed. And unfortunately many of these seed companies then re-name the seed, adding to the further confusion as to which is a Monsanto seed. 🙁

Safe Seed Marketplaces

SeedWise is a marketplace enabling seed farmers to sell directly to home gardeners, so their seeds come from a variety of regions and you can view the profiles of their seed farmers to learn more about them. The site focuses on organic and non-GMO seeds.

There are a number of seed sellers on Etsy, however you will need to research them yourself to determine whether seeds are organic, GMO-free, and don’t match the breeds shown in the Monsanto-owned list below.
