Bristlegrass is a common term used to describe several species of grass that typically have bristly seed heads. Some synonyms for bristlegrass include foxtail, feathergrass, spear grass, and timothy grass. Foxtail grass gets its name from its bushy appearance and resemblance to a fox's tail. Feathergrass is often seen growing in prairies and meadows and produces soft, feathery seed heads. Spear grass is a tough, wiry grass that can be found in dry, arid regions and produces sharp, pointed seed heads. Timothy grass is a tall, coarse grass commonly used for grazing animals and hay production and produces cylindrical seed heads. Regardless of the name, bristlegrass and its synonyms are important forage and habitat plants for many animals.
