Upland Native perennial bunch best adapted to moderately deep, deep, somewhat dry, poorly drained, sandy, or clay loam soils. It does poorly on some heavy soils. In the East, it performs well on shallow and droughty soils. Switchgrass occurs naturally on prairies, open oak and pine woodlands, shores, riverbanks, and high brackish marshes along maritime forest ecotones. One of the Big 4 Prairie grasses. Most common varieties are Alamo and Blackwell. Alamo produces more forage.
Alternate Name: Panic raide
Uses
Livestock: Switchgrass produces heavy growth during late spring and early summer. It provides good warm-season pasture and high quality hay for livestock.
Erosion Control: Switchgrass is perhaps our most valuable native grass, adapted to a wide range of sites. It stabilizes soil on strip-mine spoils, sand dunes, dikes, gullies and other critical areas. It is also suitable for low windbreak plantings in crop fields.
Wildlife: Switchgrass provides excellent nesting and cover for pheasants, quail, and rabbits. It holds up in heavy snow (particularly ‘Shelter’ and ‘Kanlow’) and is useful on shooting preserves. The seeds provide food for pheasants, quail, turkeys, dove, and songbirds. Due to its potential to spread, some wildlife biologists have reduced or eliminated the use of switchgrass in some plantings.
Biofuel Source: Switchgrass is a native perennial, warm season grass with the ability to produce moderate to high biomass yields on marginal lands. These characters have resulted in the use of switchgrass in several bioenergy conversion processes, including cellulosic ethanol production, biogas, and direct combustion for thermal energy applications.
