Timothy (Phleum pratense L.)

Cool-season grasses

Timothy is a relatively late-maturing, short-lived perennial grass that is best adapted to cool, moist regions. Timothy has a fibrous and relatively shallow root system. Because it does not develop a deep root system, it does not persist well under drought conditions. It is intolerant of hot weather but is among the most winter hardy of the cool-season grasses. Timothy’s forage quality is often better than many other cool-season grasses in the spring because it matures three to four weeks later than orchardgrass or tall fescue. Timothy is relatively easy and inexpensive to establish, but it does not compete well with other grasses. It is considered one of the more friendly grasses for wildlife habitat. Cattle like timothy, but the plants cannot survive close or frequent grazing. If you use timothy, you should practice rotational grazing.
