Narrative
Attractive, persistent, lower-growing, turf-type capable of producing a turf with fine texture, medium-high density and a reduced rate of vertical growth. Darker green color than most ryegrasses currently in commercial production. Good winterhardiness, good cold temperature color retention, and moderately good tolerance of heat and drought. Moderately good resistance to large brown patch disease (Rhizoctonia solani) and winter brown blight disease (Drechslera spp.).
