Other forms: buckwheats
Buckwheat is a plant whose triangular seeds are harvested and milled into flour. Some people prefer hearty buckwheat pancakes to the lighter and fluffier white flour version.
Despite the similar names, buckwheat isn't related to wheat — its closer cousins are rhubarb and sorrel. It grows triangular-shaped seeds that can be cooked and eaten whole or ground into flour for use in foods like Japanese soba noodles. The word comes from the Middle Dutch boecweite, "beech wheat," based on buckwheat's resemblance to the seeds of the beech tree.
