"Many gardeners today are using the word heirloom when they really mean open-pollinated or non-hybrid. Heirlooms are treasures. Heirloom seeds are the seeds for open-pollinated varieties with histories, with stories. At one time, someone, somewhere thought each heirloom was a treasure and passed on its story. However, not all open-pollinated varieties are treasures. Sometimes the original reasons have been forgotten. Sometimes they are being grown in a different climate...
Open-pollinated is the description to look for if you want to save your own seeds. Open-pollinated seeds come from relatively stable varieties resulting from pollination between genetically similar parents.
On the other hand, seeds saved from hybrid and genetically modified varieties, the opposite of open-pollinated, present a complicated challenge for seed savers. Only a small percentage of will resemble the orginal parents. Some will be sterile. Most are patented. Saving seeds from some is now illegal." - seedstrust.com
You will sometimes hear the term GMO. This means Genetically Modified Organisms. Stay away from GMO seeds, GMO plants, and GMO animal products. Genetic modification is destroying our sustainability.
