Carex sprengelii
Sprengel's Sedge
North America, from Quebec south to Virginia and west to British Columbia, in moist woodlands and streambanks
Overview
Carex sprengelii is a graceful native sedge of eastern North America, growing 18-30 inches (45-75 cm) tall and 18-24 inches (45-60 cm) wide. Named after German botanist Kurt Sprengel. Medium green narrow arching leaves create a fountain-like form that moves in breeze. Dangling spikelets in late spring add a delicate texture. The arching habit (more graceful and fountain-like than many other sedges) makes this an ornamental native sedge species. Highly adaptable: tolerates full sun to full shade, moist to average soil, and a range of pH levels. The clumping habit (not stoloniferous) stays where planted. Golden-yellow fall color. Hardy to zone 3. A native alternative to non-native ornamental grasses for shade situations. Deer avoid sedge foliage.
