Which term describes a plant that lives for more than two years?

• A. Annual
• B. Biennial
• C. Perennial
• D. Circulative

Answer: (C)

Plants that live for more than two years are called perennials. An annual completes its life cycle in one growing season and dies after producing seeds, while a biennial takes two years to finish its life cycle—often growing foliage in the first year and flowering in the second. Circulative isn’t used to describe how long a plant lives. Perennials persist across multiple seasons, regrowing each year from existing roots or crowns, which is why this term best fits a life span longer than two years. In practice, recognizing a plant as perennial helps guide long-term pest control and management strategies, since these plants can require different approaches over multiple seasons.
