Wild buckwheat is a European native. It is a vine that snakes along the ground or clambers over other plants or anything
else it can latch onto, winding itself in a clockwise direction around supports. Plants are up to 3' (1 m) long.
At points where leaves attach there is an ocrea, or sheath.
Leaves are alternate and roughly triangular to heart-shaped, with smooth edges. The lower corners of
each triangle are pointed inward toward the leaf petiole (stem). Leaves are ½-2" (1.5-6 cm) × ¼-1" (7-30 mm) wide. Flowers are small, ⅛" (4 mm) each, in long thin clusters, sort of weird-looking, greenish-white to greenish-pink.

Vine up to 3' (1 m) long. At leaf nodes there is an ocrea.
Vines up to 20' (6.1 m) long. Stems are light green to bright red, almost hairless. Where leaves attach to the stem, there is a protective sheath, or ocrea
Stems are 12-197" (30-500 cm) long. It climbs by twining around other stems, from right to left. There are stiff bristles at each node (ocrea. Each ocrea is ¹/₁₆-⅛" (3-4 mm) long.
Flowers
Small, greenish-pink to greenish-white, in racemes (bunches); individual flowers are ⅛" (4 mm) long, racemes are up to 2½" (6.3 cm) long
Racemes are 2-8" (5-20 cm) long, with small greenish flowers.
Panicles are 1½-4" (4-10 cm) long, comprised of greenish-white or pink-fringed flowers. Each flower is 5-parted. Flowers appear from June to October.
Leaves
Alternate, triangular or heart-shaped, lower corners of leaves aim inward toward the petiole (leaf stem)
Ovate, approaching sagittate (shaped like an arrowhead), up to 2" (5 cm) × 4" (10 cm). Leaf petioles are up to 1½" (3.8 cm) long
Alternate, oval to triangular, with wavy margins, often with reddish veins standing out. Their stems (petioles) are ⅜-2" (1-6 cm) long.
