Winter annuals are defined as what germination pattern?

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

Answer: (A)

Winter annuals start growing in the fall, take advantage of autumn moisture, and then complete their life cycle by spring, dying before the hot, dry summer arrives. The seeds they produce survive through the summer and wait for the next fall rains to germinate again. This pattern fits climates with wet winters and dry summers, which is why many species in Oregon show this cycle.

So, the correct description is germinating in fall and dying before summer. The other patterns describe spring annuals (germinate in spring and die before winter), summer annuals (germinate in summer and die before fall), or perennials (remain alive year-round).
