Carex xerantica, commonly known as Whitescale Sedge, is a perennial sedge that is deciduous or semi-deciduous, depending on the climate. It is native to North American prairies, meadows, and open woodlands, with a range extending into the Yukon. This sedge typically grows to a height and width of approximately 2 feet (0.6 meters), forming dense clumps of narrow, grass-like leaves. The plant produces inconspicuous brownish flower spikes in late spring to early summer, which are not particularly showy but add a subtle texture to the landscape.

Whitescale Sedge is valued for its adaptability and is used for soil stabilization, as well as in rain gardens due to its tolerance for wet conditions. It is also a suitable choice for naturalistic plantings and meadow gardens, where its foliage provides contrast and interest. In cultivation, it thrives in full sun to part shade and requires medium amounts of water, performing best in soils with slow to medium drainage. While generally low-maintenance, it can spread by rhizomes and may need to be managed to prevent unwanted naturalization.CC BY-SA 4.0
