Weeds
wire-grass, drop-seed
Muhlenbergia schreberi
Nimblewill is a warm-season turfgrass that will infest cool-season turf. It has excellent winter hardiness which allows it to establish and compete. It will often stay dormant (white-to-tan) until Memorial Day and will go dormant soon after Labor Day. Nimble will has the growth habit of bermudagrass but is hairless and somewhat more upright.
