| Identification | Common Buckwheat is most often 6 inches to a foot tall, but potentially much taller. The lower stem leaves are well-spaced, broadly triangular, taper-pointed, and sometimes vaguely 3-lobed. The upper stem leaves are smaller, narrower, sessile, and clasp the stem. The small white to pinkish flowers grow in clusters from leaf axils; for a member of the Family Polygonaceae, the flowers are rather large and attractive. The fruits are light brown, 3-angled. | |
