Note: Not all of the veggie varieties in the above list are Monsanto/Seminis exclusives. Consequently if you spot some of these varieties in the catalog of an heirloom seed-seller, just check with the seller to make sure the seeds were not purchased from Seminis/Monsanto. But if you find these seeds on a rack at a big-box garden center, you have every right to suspect they were purchased from the evil empire.
I wonder if any of these countries are unwittingly importing GMO seeds.
