Which type of plant survives year to year?

Perennial plants are characterized by their ability to survive for more than two years, often coming back each growing season as they establish extensive root systems. This resilience allows them to endure adverse conditions and re-emerge after periods of dormancy, such as winter. They can provide significant ecological benefits by contributing to soil stability and supporting biodiversity in aquatic ecosystems. On the other hand, annuals complete their life cycle in one growing season, while biennials require two years to finish theirs. Submergent plants are a category of aquatic plants that remain submerged, but their lifespan varies and is not specifically tied to being annual or perennial. Thus, perennial plants are the correct choice for demonstrating a type of plant that consistently survives year after year.
