What is a notable feature of Kentucky Bluegrass?

Kentucky Bluegrass is particularly renowned for its exceptional cold weather tolerance. This trait allows it to thrive in cooler climates, making it a popular choice for lawns and sports fields in northern regions where temperatures can drop significantly. The grass species is able to go dormant during extremely cold conditions and will revive when temperatures rise again, which is a desirable characteristic for maintaining a green lawn in areas with harsh winters.

The other characteristics mentioned do not align as closely with Kentucky Bluegrass. For example, it does not exhibit high shade tolerance compared to other grass types, nor is it known for quick establishment—it generally takes longer to germinate and develop than some other grass species. Additionally, while it can survive periods of drought, it is not specifically emphasized for high drought tolerance as some other varieties are. This makes cold weather tolerance a distinct and notable feature of Kentucky Bluegrass.
