Narrative

Winter-hardy perennial forage replacing Nebraska 50 for seed production and use primarily in the central Great Plains. Used principally as a cool-season pasture crop and sometimes hay. In central latitudes, growth begins early and extends into the summar grazin season, with good forage quality and acceptance by cattle. Seedling growth good and establishes well during cool weather of fall or spring. Plants strongly spreading by rhizomes. Show reasonable uniformity in height, leaf color, and time of flowering.
