Description of Nimblewill (Muhlenbergia schreberi):
Nimblewill is a fine textured, mat-forming perennial grass. This species is characterized by its slender stems and erect early season growth, with short, narrow leaves that jut out horizontally in different directions. Nimblewill patches turn a distinctive tan color in winter. This species reproduces by seeds and stolons (horizontal stems at the surface of the ground that root at the nodes). Nimblewill survives best on moist, rich, gravelly soil, and is often troublesome in pastures, lawns, orchards, nurseries and gardens. It is also common in waste places and roadsides. In high summer heat, it turns a grayish-silver color which makes it easy to identify.
