Perennial Ryegrass is one of the most widely used turfgrasses because of its quick germination of roughly 1 week. This fine-bladed bunchgrass is preferred by many homeowners because of its dark color, strong root system, its fast response to fertilization, and its rapid recovery from traffic. As a cool-season grass, Perennial Ryegrass can adapt to many different kinds of soils including poor soils, clay, and badly drained areas. A high level of endophytes also allows this species to perform well under stress. Perennial Ryegrass prefers full sun but will tolerate some shade and can be mowed as short as 3/16 of an inch.
