Which statement correctly compares creeping bentgrass and annual bluegrass for cold hardiness?

• A. Creeping bentgrass has greater hardiness.
• B. Annual bluegrass has greater hardiness.
• C. They have the same hardiness.
• D. It varies by region.

Answer: (A)

Cold tolerance is about how a grass handles freezing and winter stress. Creeping bentgrass is more cold-hardy than annual bluegrass. It’s adapted to very cool conditions and on golf greens it often survives harsher winters and recovers quickly after freeze–thaw cycles. Its tissues remain more stable under cold and it endures repeated frosts better, whereas annual bluegrass is more prone to winter injury and crown damage in cold conditions. So, in general, creeping bentgrass exhibits greater hardiness in cold weather, which is why that statement is the best choice.
