Carex davisii aka Davis' Sedge

Carex davisii, or Davis's sedge, belongs to the sedge family, Cyperaceae. Chicago Botanic Garden calls it awned graceful sedge. This perennial comes from the eastern-central United States. It is not native to Britain or Ireland. In Missouri, it grows in moist woods and beside streams. It also grows on rich, wooded slopes. These habitats help explain its need for a damp growing site.

The plant forms upright clumps with grass-like leaves. Clumps reach about 2.5–3 feet [0.76–0.91 metres] tall. The listed mature spread is about 2 feet [0.61 metres]. Leaves can reach half an inch across. Its upright form gives height to a low groundcover planting. The leaves provide much of its garden interest. This is a plant to choose for foliage and form, rather than showy blooms.

The flowers are green and have little ornamental impact. Missouri Botanical Garden lists flowering from May through July. Chicago Botanic Garden gives a shorter season, from May through June. Together, these records place bloom in late spring and summer. The seeds look like tiny footballs. They sit in loose clusters that do not last long. These small details reward a close look, rather than making a bold floral display.

Grow Davis's sedge in full sun or partial shade. Missouri Botanical Garden reports its best growth in wet soil. Chicago Botanic Garden lists moist soil and full sun. Give it a site that retains moisture through the growing season. The broader published hardiness range is USDA zones 4–7. Chicago lists zones 5–7. Care needs are low when the site suits the plant. Hot, dry summers can send the foliage into dormancy. Extra water may help keep the leaves in growth.

Use this sedge in rain gardens or damp native plantings. It suits wet meadows, woodland sites, and stream edges. Chicago Botanic Garden also lists it as a groundcover. Its tolerance of wet soil makes it useful in damp spots. Missouri Botanical Garden lists resistance to deer and erosion. Summer dormancy remains a concern where heat and drought coincide. The supplied sources give no species-specific pest or disease details. They also provide no evidence about edible parts or toxicity.
