Back to trial Carex (Sedges) for the Mid-Atlantic Region

Trial Garden

Appalachian Sedge (Carex appalachica)

4 Photos


Summary

Carex appalachica is a fine-textured Carex native to the Appalachian Mountains northward through New England. Aesthetically the foliage and overall dimensions of this plant resemble Carex pensylvanica, although C. appalachica is a clump-forming species rather than spreading. Appalachian sedge failed to thrive in the trial and likely would have fared better in soils that were drier and more well-drained than those in the Trial Garden. In the naturalistic gardens at Mt. Cuba Center, C. appalachica flourishes on well-drained slopes and is particularly effective when planted with other woodland plants. This species is often touted as an effective turfgrass lawn alternative, but this was not tested due to the small size and poor vigor of the specimens available at the end of the trial.
