Biennial weeds live for how many seasons?

Biennial weeds live for how many seasons?

• A. one growing season
• B. two growing seasons
• C. three growing seasons
• D. four growing seasons

Answer: (B)

Biennials complete their life cycle in two growing seasons. In the first year, the plant grows vegetatively and stores energy (often forming a rosette at or near the ground). It overwinters and then, in the second year, it uses that stored energy to send up flowering stalks, produce seeds, and then die. That two-season pattern is what defines a biennial, so the correct choice is two growing seasons. By comparison, annual weeds finish in one season, and perennials live for three or more growing seasons. A common biennial weed example is burdock, which behaves this two-year cycle.
