Water chestnut is a plant with an extensive native range, primarily found across various regions in Europe, Asia, and Africa. It has been introduced and cultivated in diverse climates, marking its presence on multiple continents. While being cultivated and valued in certain areas, water chestnut is sometimes thought to be invasive elsewhere, potentially impacting local ecosystems. Notably, in some parts of Europe and Asia, water chestnut may alter aquatic habitats, but it remains merely cultivated in most of its range without significant ecological disruption.
