Ancient Seeds for Modern Needs...
Native Seeds/SEARCH conserves, distributes and documents the adapted and diverse varieties of agricultural seeds, their wild relatives and the role these seeds play in cultures of the American Southwest and northwest Mexico. We promote the use of these ancient crops and their wild relatives by gathering, safeguarding, and distributing their seeds to farming and gardening communities. We also work to preserve knowledge about their uses.
