Both are OK.

Lotus and lotus belong to the same kind of flower, so both of them can produce lotus roots. In the true sense, lotus and lotus flowers do not produce lotus roots. The rhizome of the lotus is the lotus root, and the lotus root is a part of the lotus. Lotus root grows in mud. Its cross section has many small holes of different sizes. The purpose of these holes is to adapt to the air cavity formed in the water. After the flowers wither in autumn, the part above the water will wither, and you can dig the lotus roots at this time. Lotus root can not only be eaten raw, but can also be used in cooking. It tastes very crisp and is slightly sweet when eaten raw. Lotus root has high medicinal value and is rich in mucus protein and dietary fiber.
