Photograph of a switchgrass plant. The back of the photograph proclaims, "Switchgrass – (Panicum Virgatum) - A vigorous, native, perennial, sod-forming grass that occurs throughout most of the U. S. It is most abundant and important as a forage and pasture grass in the central and southern parts of the Great Plains. It usually grows to 3 to 5 feet high, with short, vigorous rhizomes. The flowering head is a widely branching open panicle. Leaves are green to bluish-green. It occurs on nearly all soil types but is most abundant and thrives best on moist low areas of relatively high fertility. Heavy, vigorous roots and underground stems make the species excellent for conservation use. Usually it is seeded with the species with which it occurs naturally. Growth begins in late spring and continues through the summer if there is enough moisture."
