Answer 1

You should specify which water chestnut

Chinese water chestnuts were introduced to the United States in the 1930s. Historically, states with commercial production include Florida, Georgia, and California.

To avoid confusion, growers looking into Chinese water chestnut as a commercial crop should be aware that there is an invasive, weedy wetland plant commonly known as water chestnut, Trapa natans, that has become naturalized in parts of the Eastern U.S.

T. natans, often called water chestnut or European water chestnut in the U.S., belongs to the Trapaceae family (which happens to be a monogeneric or single genus family). In contrast to the Chinese water chestnut which is harvested for its corm, the harvestable portion of T. natans is the seed or fruit—thus the common name of Singhara Nut in India and the Ling Nut in other parts of Asia. In India, Singhara Nut is considered a minor crop, and is sometimes only harvested as survival food under severe conditions.

T. natans was introduced to North America from Eurasia around 1874, and has since become a serious aquatic weed in much of the eastern U.S. and Canada. T. natans is a prohibited or restricted aquatic plant in states like South Carolina and Florida. It is illegal to import or distribute or even transport this plant through these states.
