The other morning I heard an interview of Jere Gettle on NPR. Gettle is the founder of Baker Creek Heirloom Seed Company, which is where we bought our seeds. Heirloom seeds are "pure" seeds that have not been genetically modified. Baker Creek specializes in seeds from 19th century plants. Through the years, seed companies have decided what seeds to sell and some of the vegetable varieties from the 19th century have been thought extinct. Gettle is working on bringing these varieties back by find farmers who might still be growing them.
You too can save your seeds. Doug and I have already saved seeds from okra and beans. We're going to try to save seeds from other plants. Here are Gettle's tips for saving seeds.
