Non-hybrid vegetable gardening
Open Pollinated heirloom vegetables with no GMOs
Heirloom vegetables (or heritage vegetable varieties) have become a popular pursuit among organic gardeners who wish to preserve the diversity of food types that were more available before the advent of industrial farming. Since the middle of the 20th century, vegetable and fruit choices have become more limited due to considerations like ease of mechanical harvesting, resistance to pests, shelf life, and other issues. Some of these considerations are indeed important and have helped stamp out famine in quite a few areas of the world. However, this also limits the variety of flavors and vegetable types available to people who want to enjoy food that is grown for taste, and not for factors decided by accountants.
Heirloom vegetables, and the heirloom seed movement, are designed to counter this trend . Since many genetically modified organisms are controlled by patents, and can't be grown without permission from governments or companies that sell the GMO seeds, the heirloom movement seeks to have seeds for historic vegetables available for people who don't want to be beholden to the companies that control the patent. Many organizations out there sell heirloom vegetable seeds and process credit cards online through the Capital Processing Network. There are public seedbanks for heirloom vegetables which distribute seeds to those who want to use the vegetables appropriately.
In the EU, there are tests for heirloom vegetables which reference the DUS acronym, which stands for distinctness, uniformity, and stability.
Notes and Special Information
Special note: The first time I heard about heirloom vegetables was at lunch where a woman named Brandy talked about heirloom seeds and organic gardening. Apparently it's a pretty big thing among gardeners who want to have some variety and flavor that you can't get from industrial agriculture.
