We’re a community of gardeners and seed stewards, sharing
and swapping rare seeds you might not find anywhere else.
The Exchange works to keep biodiversity
strong and garden traditions thriving.
We’re glad you’re here.
We’re a nonprofit that conserves and promotes America's culturally diverse but endangered garden and food crop heritage for future generations by collecting, growing, and sharing heirloom seeds and plants. The Exchange is one way we involve our community in fulfilling this mission.Learn More
