Perennial Percent^™

Perennial grains are long-lived alternatives to major grains like barley, lentils, and sunflower seeds.

Perennial grains allow farmers to plant once and harvest a crop for three years or more without replanting. These crops’ longevity and deep root systems build healthy soil and protect it from erosion. They also better utilize water, foster biodiversity, remove carbon from the air, and more.
