Native to the prairies of North America, Indian Grass (Sorghastrum nutans) is a tall, bunching, warm-season grass that is also used as feed for livestock.A popular ornamental grass, it works well as an upright backdrop in garden borders or as a main mass feature when creating a natural meadow or wildlife garden. The grass grows to be up to six-foot when in bloom, and the seedheads add a splash of yellow to orange color from late summer to early fall.Because the short rhizomes are able to remain standing in winter while dormant, it can continue to add interest to your garden throughout the year. The grass blades add shades of green, grey, and even blue to the landscape.As a result of its hardiness, clumping formation, strong rooting system, and ability to grow in infertile soils, Indian Grass can work well on slopes to prevent erosion.
