This small, evergreen sedge is an exceptionally blue selection of a species native to the northeastern U.S. It grows in a spreading fountain of narrow, arching leaves that are a dusty blue-green. Though it resembles an ornamental grass and is listed by some nurseries as a grass, ‘Blue Zinger’ comes from a different family, and like many of its fellow sedges, is more versatile than grasses, being tolerant of both full sun and partial sun and most soils, including moist and wet soils. It is rhizomatous (spreading by underground stems) but not invasive and one plant eventually becomes a colony, making it a good groundcover. Cutting back the leaves speeds the growth of the rhizomes and can be done three or four times a year. The leaves are evergreen in warm climates, perennial in colder climates, where they wither and brown in autumn. Remove them in late winter to make way for the new leaves in spring.
