The leaves are triangular or ovate-triangular, 2.5-7 cm long, 2-5 cm wide, acuminate at the top, heart-shaped at the base, with papillary protrusions along the veins on both sides. Buckwheat likes a cool and humid climate, is not resistant to high temperature, drought, strong wind, fears frost, likes sunshine, and needs more water
