Cool-season grasses -- including bentgrass, Kentucky bluegrass, red fescue and annual and perennial ryegrass -- grow best in areas with cold winters and a warm to hot summer.
A warm-season grass is capable of withstanding the intense summer heat of the South, but turns brown in late summer and greens up only after the return of warm weather. Warm-season grasses include Zoysia grass, Bermuda grass, centipede grass and St. Augustine grass.
For areas shaded by trees, consider Bahia grass or fine-leaf fescue. If you live in an area that's dry, consider buffalo grass or another drought-resistant variety. If your family requires a lawn that holds up well under heavy use, consider sturdy grasses such as perennial ryegrass or Kentucky bluegrass.
The American Lawns website recommends you consult your local extension service or a lawn expert to determine the best grass for your area and your particular growing situation.
