Large group of grass-like, clumping plants with low or moderate water needs that are native to many parts of the world and offer a variety of shapes, sizes, and foliage characteristics. Some sedges are ideal for use in rain gardens and swales, for stabilizing slopes, as a mass groundcover, or as part of a meadow planting. Two low-water examples that prefer some shade are Catlin sedge (C. texensis, 4-6” x 6-8”), a small, mat-like sedge native to central and southwestern North America, and Berkeley sedge (C. tumulicola, 1-2’ x 1-2’), a larger species native to western North America that tends to self-sow. Other species require more water and may be less suited to dry inland conditions. Some species can be invasive and difficult to control.
