Grasses used in Illinois are typically cool season grasses. Kentucky bluegrass, fine fescue, and perennial ryegrass are the most common with turf type fescue being used at the more southern portion of Illinois. Some people are using warm season grasses such as zoysia grass in Southern Illinois as well.
Cool-Season Grasses:
Kentucky bluegrass is by far the most popular species used in home lawns in northern Illinois, due to high quality appearance, hardiness, and recovery ability. Kentucky bluegrass spreads by rhizomes. Most cultivars of Kentucky bluegrass require moderate to high levels of maintenance (such as fertilizing, watering, etc.) to maintain high quality. Kentucky bluegrass prefers full sun, although a few cultivars have tolerance to light shade. Kentucky bluegrass is slow to establish by seed, and is also readily available as sod.
Fine fescues require less maintenance and many adapt to shade. The fine fescues include red and chewings fescues, sheep fescue, and hard fescue. Leaf width is narrow, and most are bunch-type grasses (red fescue has rhizomes). Wear tolerance (such as foot traffic) and recovery ability of fine fescues is fair. Maintenance levels are generally low, especially fertilizer needs, and fine fescues may decline in full sun when mowed frequently.

Perennial ryegrasses are bunching cool season grasses that are compatible in appearance with bluegrass, do not form thatch, have good heat tolerance and may be drought resistant. They tend to be disease prone and offer poor freezing tolerance if flooded or exposed to wind. Perennial ryegrasses is designed for full sun areas, but will tolerate some shade. Ryegrass is bred to give a pleasing dark green color, with a fine texture and excellent mowing qualities. Is also a very good choice for blends with Kentucky Bluegrass and Fine Fescue.
Tall Fescue - The new turf-type tall fescues are excellent for warmer areas of Illinois and the southern area. While they take a little while to establish or recuperate since they are a clump-type grass, they are extremely wear resistant, drought, heat, and salt-tolerant; and moderately shade tolerant. Tall fescues have few disease problems and require less maintenance that other grasses. Kentucky bluegrass is the first grass to brown out in the summer and tall fescue is the last.
