Nimblewill is a perennial grass that browns in the winter. Nimblewill produces short stolons, but no rhizomes. The leaves are rolled in the bud, the ligule is short, membranous, toothed at the top, and auricles are absent. The leaf blades are narrow and white-green in color. Nimblewill forms patches and is fairly tolerant of shade. The seed head is a loose spike-like panicle. Nimblewill is found through most of the Eastern United States.
Nimblewill is a perennial that goes off color with cool weather. Nimblewill is aggressive where the turf is not fertilized. Nimblewill is more aggressive in shaded areas. Turf that is mowed low will resist the invasion of nimblewill. Nimblewill is more aggressive in moist rich soil.
