Summer annuals germinate in which season and reproduce when?

• A. Germinate in the spring, then flower and reproduce in late summer/early fall.
• B. Germinate in winter, flower in spring
• C. Germinate in fall, reproduce in winter
• D. Germinate in summer, reproduce in fall.

Answer: (A)

Summer annuals start life when soils warm in spring, needing warm temperatures and moisture to germinate. They then grow through the spring and summer and reach flowering and seed production by late summer to early fall, finishing their life cycle before frost. So they germinate in spring and reproduce in late summer or early fall. This timing lets their seeds mature before winter and aligns with their nature of completing their life cycle in a single season.
