What is a distinct feature of the duck potato plant, known for its white, 3-petaled flowers?

The distinct feature of the duck potato plant is that it has broad, sword-shaped leaves. This characteristic leaf shape differentiates it from other aquatic plants, which may have various leaf forms. The sword-like appearance allows the plant to efficiently capture sunlight and thrive in its wetland habitat.

While other features, such as the thick creeping roots or the height, may be true for some aquatic plants, they do not define the duck potato specifically in the same way that the shape of the leaves does. The unique sword shape is a key identifying characteristic that makes it easier to recognize the duck potato among other vegetation in aquatic environments.
