Unlike many other perennial sedges, this sedge is easier to control because it is a true annual. Annual sedge has a very characteristic seedhead that tends to be relatively large compared to other sedges; the seedhead is flattened with a toothed outline. Annual sedge tends to grow in clumps more often than other sedges, particularly when it occurs in low densities. This sedge tends to emerge later in the spring/summer than most other sedge species; active growth period is in summer and fall. Growth of annual sedge can be rapid and height at full maturity can reach 1 foot.
