- Genus & species
eastern star sedge
Eastern North America — from Quebec south to Georgia and west to Minnesota, in moist woodlands and meadow edges
Overview
Carex radiata is eastern star sedge in the Cyperaceae family — a versatile and adaptable native sedge growing 10-18 inches (25-45 cm) tall and 12-18 inches (30-45 cm) wide. The species name 'radiata' means 'radiating', describing the star-like spreading pattern of the spikelets. Medium green narrow arching narrow-textured leaves form a graceful clump. The star-like radiating spikelets in late spring add a delicate detail. Extremely adaptable: sun to full shade, moist to average soil, clay-tolerant, drought-tolerant once established. Clumping (not spreading). Hardy to zone 3. The versatility and reliability make this a strong all-purpose native sedge — it performs reliably in conditions that stress more specialized species. Semi-evergreen. Golden-yellow fall color. Deer avoid sedge foliage.
