In a way, I was kind of hoping you weren't going to say a Southern state. There are a lot of invasive species down there. So it makes identifying any particular plant more challenging. Plants like Hygrophila polysperma have really choked out some waterways down there. It's not to say that the Northern states don't have invasive species, but usually aquatic plants purchased for aquariums over seas are of the tropical type and cannot survive over winter.
I'll still look and see what I can find. I still have no idea, lol. The good news is that your plant has a much better chance to survive in the aquarium environment since it's not from a colder climate.
