Summer annuals are defined as what germination pattern?

• A. Germinate in spring, die before fall
• B. Germinate in fall, die before summer
• C. Germinate in winter, die before spring
• D. Persist year-round

Answer: (A)

Summer annuals complete their life cycle within one growing season. They germinate in spring, grow through the warm months, produce seeds, and die before the cold season arrives, so they don’t survive into winter. That’s why germinating in spring and dying before fall (i.e., before winter) best describes their pattern. This pattern means you’ll typically see them emerge in spring, set seed in late summer, and then die as temperatures drop, helping distinguish them from winter annuals or perennials.
