Which statement best describes annual bluegrass in the southern U.S.?

• A. It exists as winter annual only
• B. It exists as winter and summer annual
• C. It is a perennial weed
• D. It is not present in the southern U.S.

Answer: (A)

Annual bluegrass in the southern U.S. behaves as a winter annual: it germinates in fall, grows through the cool winter, and completes its life cycle by spring, dying or becoming inactive as summer heat arrives. This pattern means it does not persist as a summer annual or survive as a perennial, and it is indeed present in the South. Hence, describing it as a winter annual only best fits its behavior in this region.
