You can think of heirlooms as "purebred" plant species. An heirloom seed is from a species of plant that has been carefully grown and saved for many generations. The value could lie in its flavor, productivity, hardiness, or adaptability. Many heirlooms have been preserved for more than 100 years. Some have history reaching back 300 years or more. To be preserved for so long, these seed varieties have had to prove their value to many peoples across time and place. Most heirlooms have been saved and selected because they have the best flavor and production in home and small market gardens. Learn more at www.rareseeds.com.
