Bacopa caroliniana, also known as lemon bacopa, is a popular aquatic plant. It is mostly found in the southeastern United States. Also, it can be found as a submergent plant or an emergent one.
It tends to grow near shorelines and sometimes in water that is less than 3 inches deep. Lemon bacopa has a single stem with opposite leaf growth. The leaves are thick and juicy. The reason some people enjoy and even encourage planting this plant is the pretty, attractive, purple-blue flower that sprouts. They are a popular plant used to add beauty to water gardens and to provide habitat in wetland enhancement as well as restoration projects.
