Origin:

May be Eurasian in origin, but now found worldwide, including throughout the United States and southern Canada.

Biology:

An annual that forms low mats of foliage and thrives in wet soils. It has a fibrous root system and the foliage has the scent of celery. It is found in poorly drained settings in landscape or turf, as well as along roadsides.

Identification:

Individual plants are slender, with several stems arising from the crown and growing to 8 inches tall. This height is diminished in thick clumps, and the denseness of the clumps gives the appearance of a single, widely spread plant. Stems are slender and smooth. Leaves arise off the stems, and there may be 2 or 3 grass-like leaves. These are only 1/8 inch wide and have a rough feel to their margins. Flowers form as clusters of spikelets, each with 6 to 10 flowers. The first cluster forms at the stem at the junction of lateral leaves, and from this additional stalks may grow with a flower cluster at their ends. The cluster is compact and spikelets are not stalked.

Characteristicts Important to Control:

Annual weeds that reproduce from seeds. Physical removal is difficult due to the fibrous root system. Plants form mats that crowd out turf and may be tolerant of close mowing, forming some seed heads laterally and close to the soil. Closely resemble grasses, but biologically the sedges are broadleaf plants, and selective herbicides should be chosen with this in mind.
