Introduced from Eurasia, now found throughout the United States.
The name is derived from the disagreeable odor given off by secretions from small glands on the leaves and spikelets.
An annual grass weed, reproducing from seeds.
Mature stems may be as long as 2 feet, but tend to grow somewhat laterally, giving the plant a spreading, low appearance. Stems are hollow and hairless.
Leaves are flat or folded and about 1/4 inch wide and 3 to 4 inches long. The sheath at the stem is open, exposing a length of the stem below the leaf base. The ligule is a fringe of long, straight hairs.
Flower heads are large, open clusters of branches, and may be up to 9 inches long. The branches are composed of numerous spikelets of several seeds each, and typical of the "lovegrass" group has an appearance similar to the rattles of a rattlesnake.
Characteristicts Important to Control:
An annual weed reproducing only from seed. Physical removal, cultivation into the soil, or mowing prior to seed maturation will reduce the weeds.
