Botanical Name

CAREX tumulicola

Plant Common Name

Splitawn Sedge

General Description

Native to dry soils in the northwestern U.S., this sedge grows in a spreading, cascading clump of narrow green leaves. Though it resembles an ornamental grass and is listed by some nurseries as a grass, it belongs to a different family, and like many of its fellow sedges, is more versatile than most grasses, being tolerant of both full sun and partial to fairly deep shade (even under trees) and most soils, including somewhat dry, moist and wet soils. In mild climates, it is evergreen. It is rhizomatous (spreading by underground stems) but not invasive and one plant eventually becomes a colony, making it a good ground cover. The flowers are nondescript, appearing in clusters on thin, tall stems and should be cut off to prevent re-seeding. Some nurseries sell by this name a different sedge, Carex divulsa, that is similar.

Grow Berkeley sedge for contrasts of texture and habit in containers, mixed beds and mixed borders. Or plant it as edging for walkways, or massed as a groundcover in a wet woodland.
