Common Name: sedge, annual
Species: Cyperus compressus L.
Bayer Code: CYPCP

This species is one of the few sedge species that is a true annual. As a result, this sedge is easier to control than many other perennial sedges. Annual sedge has a very characteristic seedhead that tends to be relatively large compared to other sedges, and the seedhead is flattened with a toothed outline. Annual sedge tends to have a more "clumpy" appearance than other sedges particularly when it occurs in low densities. This sedge also tends to emerge later in the spring/summer than most other sedge species.
