Native to North America, where it occurs from Arizona to Texas, and occasionally found as an introduced grass in the area of New York. It also occurs throughout Mexico and into South America.
A perennial grass which dies back in colder winters, with re-growth from the roots. Reproduction is from seeds. Plants are considered valuable animal forage and of value for erosion control and re-vegetation of areas scarred by fires. Large stands along roadsides are potentially a nuisance that may need control.
Mature plants may grow to over 2 feet in height, forming thick stands that crowd out other vegetation. Individual plants have multiple stems arising from the base, with the long, drooping leaves arising from along the stems. Each stem terminates with the distinctive seed head, consisting of 8 to 10 long, soft branches that are lined with the flowers. Each flower has a long awn attached to it, and the flower head has the tendency to keep all the branches very close together, in a long, compact grouping. Similar to Feather Fingergrass, but the flower head stays closed and elongate.
Characteristicts Important to Control:
Control is not normally a concern, except where the plants are encroaching on roadsides. A non-selective herbicide will prevent seed germination in these cases, and a non-selective, systemic post-emergent herbicide will eliminate existing plants.
