Switchgrass is a rhizomatous perennial bunchgrass native to parts of South Texas. It is considered a climax co-dominant of lowland clay sites and of upland sandy range sites. It is found in two distinct growth forms. The first being a colonial form with numerous stalks and bright green leaves; it is found almost entirely on sand or sandy loam soils in the sand sheet. The second is an upright bushy form found in lowlands along creeks, rivers, and other riparian areas. This form is more blue-green in color and is restricted to heavy clay and clay-loam soils. Switchgrass is good forage for livestock and wildlife readily eat the seeds and use the foliage for nesting and loafing cover. Switchgrass responds well to prescribed fire. It produces numerous seed stalks in late summer and seed matures throughout the fall. Seed is occasionally produced in spring or early summer if adequate moisture is available. Production plots of switchgrass produce an average of 300 pounds per acre.
