Green needlegrass is a long-lived, cool-season, bunchgrass that is well adapted to clay textures but can also grow on medium to coarse textures. It can be fairly drought-tolerant and fairly salt and alkali-tolerant. It is also winter-hardy. Green needlegrass has a good forage yield and is quite palatable while green. It is moderately tolerant to grazing and is valuable for rangeland and pasture improvement, reclamation, and soil stabilization of disturbed sites.

Green needlegrass is native to North America and can be found from British Columbia, down through the western United States, and into Mexico. It is typically found in grasslands, savannas, and open forests, and can grow up to three feet tall. The leaves of green needlegrass are long and narrow, with a distinctive blue-green color.

In terms of management, green needlegrass is best planted in the fall or early spring, and requires adequate moisture during establishment. Once established, it can tolerate moderate grazing, but should not be overgrazed. Green needlegrass is also a good candidate for reseeding disturbed sites, such as those that have been impacted by mining or construction activities. Overall, green needlegrass is a valuable grass species for improving rangeland and pasture productivity, as well as for restoring disturbed sites.
