The difference between wild buckwheat and buckwheat

1. Leaves

The leaves of wild buckwheat are single leaves that grow alternately. The petiole is about 9 cm long, shorter in the upper part, with shorter white hairs, and is halberd-shaped triangular in shape, about the same length and width. It is green on the upper side and light green on the lower side. It is 2-7 cm long, heart-shaped at the base, and the stipules are about 5 mm long.

The leaves of wild buckwheat are halberd-shaped triangles, with approximately equal length and width; they are heart-shaped, with a sharper tip than wild buckwheat, and have white hairs on the veins.

2. Flowers

The pedicel of wild buckwheat is about 5 cm long, and the bracts are generally oval, about 2.5 mm long, and green. There are about 3-5 flowers in each bract, which are white or light pink. The flowering period is from May to September.

The pedicels of Fagopyrum serrata are between 4 and 8 cm long and have short white hairs. The inflorescences are terminal or axillary, and the flowering period is from September to October.
