Germination Dates 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.
