What does a biennial weed do?

• A. Seeds every year
• B. Seeds the second summer and die in the winter
• C. Seeds the first summer and die in the winter
• D. Remains evergreen

Answer: (B)

Biennial weeds complete their life cycle in two growing seasons. In the first year they establish and store energy. In the second year they bolt, flower, and produce seeds, then die, often by winter. So the behavior described—seeding in the second year and dying afterward—fits a biennial weed. It doesn’t seed every year (that would be an annual) and it isn’t evergreen (biennials aren’t typically evergreen).
