These produce a matted and tufted growth pattern. First a long rhizome emerges and a shoot is produced. Dead shoots with living roots can still establish daughter shoots from rhizomes. Beaked sedge also reproduces with stolons. Beaked sedge shoots can be spread by fragmentation.
Ice can break off old shoots with associated roots.
Shoots may be transported by water and caught by floating mats or end up on the shore. Flora primordia develop in August or September.
