Cool Season Grasses

Cool season turf grasses are common in the Intermountain West and Great Basin Province. Cool season grasses are suitable for temperate and colder climates. They grow best in spring and summer and go almost dormant in the winter when temperatures decline. There are many varieties, most of which are bunchgrasses. Many Cool Season grasses are turf grasses. The roots of cool season grasses can grow at 50 degrees Fahrenheit but slows when temperatures exceed 90 or drop to 32 degrees Fahrenheit.
