What is a Cool Season Grass?
 The name "Cool Season Grass" is given to a variety of grass species that thrive best in the cooler regions of the country. These grasses can include forage and range grasses, ornamental grasses, turf grasses, and grassy weeds. Grass seeds are planted in the fall and will thrive best in temperatures between 65 and 75 degrees. In contrast, warm season grass seeds are planted in the spring and grow best in the warmest months. The preferred climate zone of adaptation for cool season grasses will be in the northern half of the U.S. Click here to see the

Cool season turfgrasses include bluegrasses, fescues, and ryegrasses. Popular forage grasses include orchardgrass, timothy, and brome. These forage grasses can also be found in lawns, but are usually considered a weed. Tall fescue grass and the ryegrasses have forage varieties that do not perform well as a turfgrass. Each of the turf grasses have different characteristics that separate them from other grasses. The most noticeable is its color. However, blade width, growth habits, turf density, and its ability to withstand heavy traffic are also important. Most can withstand harsh winters and a few are able to survive longer periods of hot, humid weather. If you live in a cooler part of the country, there is a grass type that will work well for you. Cool season grasses can be started from seed much easier than most warm season grasses and the seed is generally much less expensive. Bluegrass seed and rye grass seed are among the least expensive.
