DESCRIPTION:
Wild buckwheat, also known as black bindweed, is an annual weed with arrowhead-shaped leaves. It has trailing stems, often mistaken for field bindweed, but with leaves that are more pointed. Stems can be 8 to 40 inches (20 - 100 cm) long. Clusters of inconspicuous, green flowers form in leaf axils or at the end of stems. Cotyledons are long and broad with a granular bloom and rounded tips. First true leaves are arrowhead-shaped with a rough stalk that forms a tight sheath around the stem at the base.
