- Description
-
Creeping broadleaf sedge is an herbaceous perennial in the sedge family (Cyperaceae) native to eastern Asia and naturalized in central Russia. The species epithet is derived from the Ancient Greek word for “iron,” but the reference was not explained.
This sedge grows in partial to full shade on moist soils. It tolerates wet planting sites very well.
Creeping broadleaf sedge spreads by rhizomes, although it is easily managed and controlled. The sedge can form a dense colony of plants with wide, strappy leaves. It is readily propagated by division.
Mass plant it along woodland borders or shade gardens. Its coarse texture works well as an accent plant in small spaces. It can be planted along a pond or riparian margin. It would work well in an Asian garden or rain garden.
Insects, Diseases, and Other Plant Problems: No serious problems.
