Origin:

Native to North America, and found throughout the U.S. from the Midwest to the east coast, into Canada and south into Mexico.

Biology:

A mat-forming perennial with stems that may lay along the soil, acting as stolons and rooting at the nodes. Young plants have erect stems, but as they mature they branch and begin bending and spreading. Reproduction is from seeds and stolons.

Identification:

Mature plants have many branches and stems that lay along the soil, although plants may attain a height of about 2 feet in unmowed areas. Color is a grayish green. Leaf blades are short compared with many other grasses, and are generally smooth and without hairs. The collar at the base of the leaf blade is smooth except for a line of hairs along the edges. Seed heads are thin spikes that arise either at the end of the stem or from the leaf axils. Spikelets are short and have a single short awn. Plants will turn brown in the winter, and stolons on the soil will re-sprout the following spring.

Characteristicts Important to Control:

In turf no selective post-emergent is available, and a non-selective systemic herbicide may be needed. Pre-emergent control is limited due to the growth from stolons.
