Fagopyrum is a genus of flowering plants in the family Polygonaceae, commonly known as buckwheat. It includes several species, with Fagopyrum esculentum being the most widely cultivated for its edible seeds. Buckwheat is not a true cereal grain but is often used as a grain substitute due to its high nutritional value, including protein and fiber. The plant is typically grown in temperate regions and thrives in well-drained soil. Buckwheat is also valued for its ability to improve soil health by suppressing weeds and enhancing soil structure. Its flowers attract pollinators, making it beneficial for biodiversity in agricultural systems.
