Lower growing with high tillering capabilities, perennial ryegrass is cross-pollinated with a branched root system. Seedheads will not form in the establishment year. Tetraploid varieties are taller, less dense, and are more digestible with additional soluble sugars, making them better suited as a mixture component. Shiny and dark green with smooth leaves, perennial ryegrass can grow up to 2 – 3 ft. tall.

Perennial ryegrass can survive on a wide range of soils and under a wide range of climatic conditions. Perennial ryegrass will grow best on well-drained, fertile soils. Historically, perennial ryegrass has not been as productive during cold winters in the north or hot summers in the lower south. Soils with a pH below 5.5 will limit the growth of perennial ryegrass.

More persistent than annual ryegrass, but less than other cool-season grass species.

Susceptible to a ‘summer slump’ as temperatures rise.
