Potamogeton oxyphyllus

Potamogeton oxyphyllus, a perennial aquatic plant, thrives in environments with full sun and heavy clay soil, though it can adapt to lighter sandy or medium soils as well. Native to regions including China North-Central, South-Central, and Southeast, Japan, Korea, Manchuria, Primorye, Sumatera, and Taiwan, this plant is known for its edible parts—leaves, roots, and stems—which are often utilized in culinary dishes. Its distinctive feature lies in its ability to grow in a variety of soil types while thriving best in water-rich environments.
