Needlegrass (Stipa spp, also referred to as Hesperostipa comata) is an erect to ascending perennial bunchgrass native to North America, especially the western third.
The grass is not toxic to horses, but it can cause mechanical injury to the oral tissues inside their mouth. Initially horses may demonstrate excessive salivation, but once the awns become embedded inside the tissues of their mouth, it causes ulcers to form.
