Sorghastrum nutans, commonly known as either Indiangrass or yellow Indiangrass,[2] is a North American prairie grass found in the central and eastern United States and Canada, especially in the Great Plains and tallgrass prairies.
Description
Yellow Indiangrass
Sorghastrum nutans is a perennial bunchgrass, prominent in the tallgrass prairie ecoregion, along with big bluestem (Andropogon gerardi), little bluestem (Schizachyrium scoparium) and switchgrass (Panicum virgatum).
It is adapted in the United States from the southern border to Canada and from the eastern seaboard to Montana, Wyoming and Utah.[3]
It is the official state grass of both Oklahoma and South Carolina.
Ecology
Yellow Indiangrass is native to prairie habitats. Its blooming period is in late spring. It is intolerant to shade. It is also common in areas of longleaf pine. The grass grows 3 feet (0.91 m) to 7 feet (2.1 m) tall, and is distinguished by a "rifle-sight" ligule where the leaf blade attaches to the leaf sheath. The leaf is about 3 feet (0.91 m) long. The seed head contains about 175,000 seeds per pound.[3]
It regrows with renewed vitality after fires, so controlled burns are used, replacing extirpated large herbivores (i.e. bison), for habitat renewal.
