Buckwheat is a fast-growing, warm-season annual that produces clusters of small white flowers and triangular seeds. It’s commonly grown as a cover crop to improve soil health, suppress weeds, and attract pollinators. Mature plants reach about 2–4 feet tall and thrive in poor soils, making them an excellent choice for regenerative gardening.

Companion Planting Tips:
Good Companions: Buckwheat pairs well with vegetables like squash and beans, as it attracts pollinators and improves soil.
