''Festuca idahoensis'' is a species of grass known by the common names Idaho fescue and blue bunchgrass. It is native to western North America, where it is widespread and common. It can be found in many ecosystems, from shady forests to open plains grasslands. This fescue is a densely clumping long-lived perennial bunch grass with stems from about 30 to 80 centimeters in height.〔''Jepson Manual''. 1993〕 The stiff, short, rolling leaves are mostly located near the base of the tuft. The inflorescence has hairy spikelets which produce large awned fruits. The root system is thick and penetrates deeply into the soil. The roots have symbiotic mycorrhizae. There are no rhizomes; the plant reproduces from seeds and from budding with tillers. This is a nutritious and preferred forage grass for wild and domestic animals. Typical native grass associates in the far west coastal prairies are ''Danthonia californica, Deschampsia caespitosa and ''Nassella pulchra''.〔C. Michael Hogan. 2009〕 Cultivars, such as "Siskiyou Blue," are produced in the horticulture industry for landscape design and garden use. ==See also== *California coastal prairie * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Festuca idahoensis」の詳細全文を読む スポンサード リンク
