Leaves: long, narrow, straight, few per stem
Roots: underground rootstock (stolons)
Flowers: green to brown, small dense heads at the tip of fertile stems, visible April - May
Seeds: Enclosed in an onion-shaped, ribbed nutlet about 1/8 inch in length.
Seedling:
Reproduction: perennialPropagation: Spring shoots arise from stolons produced mid to late summer the previous year.

State: Can be found in wet areas throughout Wisconsin.National: Found in the northern plains and Great Lake states.
Origin:
Common to bogs, wetlands and marshes, where it prefers wettest areas. Creeping sedge may seriously compete with cranberry vines for light in a heavy infestation. Often found on cranberry beds.
While scouting a cranberry bed for disease and insect pests, identify weed populations as they arise. Note the specie(s) of weed present as well as the population level relative to field area. Example: 30% creeping sedge, 10% boneset and joe-pye weed mix.
