Perennial Promise grows healthy food for our community and healthy ecosystems on the land.

The Perennial Promise Grower’s Cooperative is an ingredients company.

We provide farmer-led, collective marketing and technical support to the growers of Kernza®—a climate beneficial perennial crop.

It will take more than a cooperative to regenerate our soils and food system—it will take all of us.

The soil is the great connector of lives, the source and destination of all. It is the healer and restorer and resurrector, by which disease passes into health, age into youth, death into life. Without proper care for it we can have no community, because without proper care for it we can have no life.

—Wendell Berry
