Most cool-season grasses have biennial life cycles.

• A. True
• B. False
• C. Some have annual life cycles
• D. Some are perennial

Answer: (B)

Cool-season turfgrasses are typically perennial, meaning they persist for multiple growing seasons and regrow each year from crowns, rhizomes, or stolons. A biennial life cycle—completing growth in two years and often dying after seed production—is not characteristic of these grasses. Some cool-season grasses can behave as annuals or short-lived perennials under certain conditions (for example, Poa annua can act like an annual weed in turf), but that doesn’t describe most cool-season species. So, the statement is false.
