Polygonatum macranthum or Big Footed Solomon's Seal (scientific name: Polygonatum macranthum) is a perennial herb of the family Asparagaceae, native to Japan, the Korean Peninsula and China.

The height of the grass is 100-150 cm. The leaves are oval with a pointed tip and produce drooping flowers of the same size as the narcissus, with about 40 flowers per plant.
