About Muhlenbergia schreberi J.F.Gmel.
Muhlenbergia schreberi J.F.Gmel., commonly called nimblewill, produces purple to green erect culms. Its spikelets measure 2 to 8 inches long, and it bears greenish panicles that contain a rachis. Each spikelet has 1 to 2 glumes that are 0.2 mm long. After spikelets mature, they disarticulate and fall to the ground. The florets of nimblewill are pollinated by wind. In terms of ecology, this species is eaten by the bug Stenodema vicinum, as well as cattle and other hoofed herbivores. Several other insects also feed on nimblewill, including Hysteroneura setariae, Conocephalus brevipennis, and Hymenarcys nervosa. Birds that eat this plant include tree sparrows, song sparrows, and turkeys. Its seeds can be distributed by sticking to animal hoofs or human shoes. Nimblewill grows in full light sun and partial shade, and prefers moist, loamy soil. It is a native species common in Illinois, and is sometimes found in Minnesota.
