Narrative
Attractive, moderately dark green, turf-type that produces a leafy, persistent turf of greater density, finer texture and a slower rate of vertical growth than many other perennial ryegrasses. Moderately good resistance to both the late fall and winter brown blight disease (Helminthosporium siccans) and the larger brown patch disease (Rhizoctonia solani). Good seedling vigor and establishes well on a wide range of soils.
