Which aquatic plant has a life cycle classified as perennial and produces white flowers?

The white waterbuttercup is classified as a perennial aquatic plant, meaning it lives for more than two years and typically regrows each season from its root system. This plant is known for producing striking white flowers, which can serve as a key identification feature. Perennial plants like the white waterbuttercup can offer benefits in aquatic ecosystems, such as stabilizing sediments and providing habitat for aquatic organisms.

Understanding these characteristics is vital for properly identifying aquatic plants and managing aquatic environments effectively.
