Festuca idahoensis

Festuca idahoensis

Idaho fescue

Cool season, drought-tolerant perennial bunchgrass. Most adapted to deep, fertile, heavy soils, but will occur on thin welldrained coarse sites. Seedlings are weakly competitive but once established mature stands are strongly competitive. Good palatability to livestock and wildlife.

Varieties: 
Joseph

A synthetic variety developed from 13 clones. Performs better than the one-line strains in terms of seed productivity, seedling vigor and germination. Taller, more uniform and achieves greater basal density than the original parents. (Released 1983, source of ecotype: Idaho)

Nezpurs

A synthetic variety developed from 90 clones. High seed producer with good seedling vigor and germination. More variability in plant type than Joseph. (Released 1983, source of ecotype: Idaho and Washington)

Winchester

A non-synthetic, source identified variety type. Displays a high degree of variability in its characteristics, making it adaptable to various ecological situations. (Released 1998, source of ecotype: Lewis County, ID, Winchester)
