DescriptionThe University of Idaho initiated a breeding program in 1950 to produce Idaho fescue cultivars with improved seed set, larger seed size (seedling vigor), and improved germination percentage.

Adapted to Idaho, Washington, Oregon, Montana and Colorado rangeland and open forestland with elevation between 300 and 2700 m (984 to 8856 ft.) and annual precipitation between 35 and 76 cm (14 to 30 in).
