Sun and Shade Grass: Lawn grasses vary in the amount of sun they need to stay healthy, look great and perform well. Some types need full, direct sun all day to do their very best. That can be a problem when your landscape is a mix of sun and shade. Shade trees, shrubs and buildings all create shady areas that shift throughout the day and throughout the year.

Whether establishing a new lawn or maintaining an existing one, matching the best cool- or warm-season grasses to your growing region is critical. Choosing the Pennington grass seed that's suited to your location and goals will help you achieve desired results. By choosing premium lawn grasses designed specifically for regional factors such as humidity, aridity and elevation, you ensure your lawn has every advantage for success:

Northeast Region: Cool-season grasses, such as bluegrasses, ryegrasses and fescues, prevail in the Northeast region of the United States. Northeast lawns need grasses that prefer cool temperatures and naturally resist diseases prevalent in this region. Read more about Northeast region grass seed recommendations in our seed resources.

Midwest Region: The Midwest heartland is a cool-season growing region with humidity levels that vary. The Midwest's eastern states experience humidity similar to the Northeast, but in western states encounter arid conditions. Bluegrasses dominate, but ryegrasses and fescues also do well with sufficient irrigation in the region's more arid western portions. Read more about Midwest region grass seed recommendations in our seed resources.

Southeast Region: Heat and humidity in the Southeast region create a warm, humid zone that stretches from the Atlantic Coast into Texas. Warm-season grasses dominate in this climate. Bermudagrass is the leading lawn grass in the Southeast and across the U.S. southern tier. Read more about Southeast region grass seed recommendations in our seed resources.

Deep South and Gulf Coast Region: Where high heat and humidity intensify in the Deep South and Gulf Coast, Bahiagrass and Centipede grass are common. Extremely drought and heat tolerant, these grasses stand up to the region's climate and water restrictions. Read more about Deep South and Gulf Coast region grass seed recommendations in our seed resources.

Southwest Region: Beginning in Texas and stretching into Southern California, this region combines saline water and alkaline soil with intense sunlight, high temperatures and varying elevations. Resilient Bermudagrass is widely used in the region, but sufficient watering is essential. Read more about Southwest region grass seed recommendations in our seed resources.

Pacific Northwest Region: Like the Midwest, the West/Northwest region presents diverse growing conditions. Cool, arid inland areas from Montana and Wyoming westward welcome cool-season grasses when adequately irrigated. In this area, east of the Cascade Mountain Range extending from Washington to Northern California, bluegrasses and tall fescues are preferred. West of the Cascades, cool temperatures and the humidity of the coastal Pacific Northwest create conditions similar to the Northeast. Read more about Pacific Northwest region grass seed recommendations in our seed resources.

Transition Region: Known to lawn care professionals and enthusiasts as the transition zone, this area covers the central tier of states from the Atlantic Coast west through Kansas. Different climatic zones —cool, warm, humid and arid — collide in this region. Winters are too cold for warm-season grass survival, and summers are too hot for cool-season types.
