Winter annuals germinate in which season and when do they reproduce?

• A. Germinate in the fall, remain dormant through the winter, then flower/reproduce mid-late spring.
• B. Germinate in spring, reproduce in summer
• C. Germinate in summer, reproduce in fall
• D. Germinate in fall and reproduce in winter.

Answer: (A)

Winter annuals start life in the fall, survive the winter in a dormant or vegetative state, and then resume growth in the spring to flower and set seeds before dying. This pattern fits: germinate in fall, overwinter, and reproduce in mid-late spring. It avoids the heat of summer and uses the moisture available in early spring. The other options describe patterns for spring or warm-season annuals and include scenarios (spring germination with summer reproduction, or summer germination with fall reproduction) that don’t match the winter-annual life cycle.
