Anyone who is interested in organic gardening has most likely heard of heirloom seeds. With all the talk of GMO seeds, heirloom seeds (those that are passed down from one generation to the next) are very much in demand by gardeners who want a "true" vegetable.
My great grandmother was an avid gardener. I can barely remember her, but I do remember her garden. She was also a seed saver and she passed her seeds to her daughter who did the same.
