Since 1975, we have grown, saved, and shared heirloom seeds and led a movement to protect biodiversity and preserve heirloom varieties. At the heart of our organization is a seed bank that houses a collection of 20,000+ rare, open-pollinated varieties. With gardeners like you, we can get these seeds where they belong—in gardens and on tables everywhere, for generations to come.
Through our catalog and online store, we get varieties out of our seed bank and growing. Sales support our nonprofit work.
Thank you for growing with us.

During the first and second World Wars, people started victory gardens of their own herbs and vegetables to reduce strain on the food system. Now, victory gardens are back, so we’ve created a guide of where you can find heirloom seeds within your region in North America.
As the pandemic reveals how vulnerable we are when we’re reliant on a centralized, exploitative food system, those of us who are inclined to grow some of our own food should try and prioritize buying heirloom seeds—often they taste better, they may be more nutritious, and diversifying our food varieties will ultimately be better for our collective health.
“‘Heirloom’ describes a seed’s heritage, specifically a documented heritage of being passed down from generation to generation within a family or community. An heirloom variety of vegetable, fruit, or flower must be open-pollinated—or pollinated by insects, birds, wind, or other natural means—and ‘breed true,’ or retain its original traits from one generation to the next.”

Before we go into that, you may be curious what we mean by “heirloom seeds” and their significance. According to Seed Savers Exchange:
