Pros and Cons of Ricefield Flat Sedge
Ricefield flat sedge is non-native to the United States, and tends to disrupt the ecosystem by pushing the native species out of their habitat.
This plant is not native to North America, but has naturalized in much of the United States. While it is not illegal to possess this plant in Texas, it should not be introduced into new water bodies and should be treated with herbicide when present.
