Buckwheat

Fagopyrum esculentum
Buckwheat is an annual herb (up to 0.7 m), with soft-textured, heart-shaped leaves and small white or pinkish flowers arranged in clusters at the tips of the stems. The fruits are small, strongly angular nutlets with a floury endosperm, known as buckwheat. It is a pseudo cereal, the flour of which has been used since ancient times.
