Indian swampweed is native in India and is uncommon in the United States.

Introduced populations from the aquarium trade have been discovered in Texas.
Pros and Cons of Indian Swampweed
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.
