American Grass

Eastern States

Many of these states are in or partially in the Transition Zone. The Transition Zone that can support both Warm-Season and Cool-Season Grasses.

Suitable grasses for this area

Warm-season grasses are tropical in origin and thrive during the scorching summer heat typically seen in the southern states. They are not green during the cold spells of winter. Their leaves turn brown in late fall and don't green up again until warm weather returns. In general they are green a little over half the year.

Warm-season grasses are best suited for lower and middle South regions which includes the Coastal areas from Virginia south. Zoysia grass and more cold-tolerant grasses such as Bermuda can be grown in the upper South which includes the mountainous regions from Virginia.

Cool-season grasses are most actively growing in the spring and fall when soil temperatures are 65 degrees or lower. There are 4 major types of cool-season grasses: bluegrasses, fescues, and ryegrasses. On average, areas of the country that are suitable for cool season grasses have cold winters with temperatures that fall below freezing and warm summers, without extended hot periods.

Transitional zone grasses are either Warm Season or Cool Season grasses. In general, lawns in the Transition Zone see more success with cool-season grasses over the warm season varieties. Additional factors such as altitude, the amount of sun or shade, the amount of foot traffic and availability of water may affect the success of a turfgrass variety.
