Koeleria macrantha (Prairie junegrass)

Formerly K. cristata. Cool season, drought tolerant, medium-lived perennial bunchgrass adapted to moderately or well-drained soils. Cold and heat tolerant. Widely distributed; occurs in numerous native plant communities on rangelands, meadows, plains and open forestlands; up to 11,500 ft. elevation. Starts growth very early in spring and provides excellent early season forage for livestock and wildlife. Establishes easily and is a good choice for revegetating severely disturbed areas. Often used in native restoration as well as revegetating mined lands, heavy use areas and other disturbed soil surfaces. Varieties listed below.
