Carex flacca

Carex flacca, with common names blue sedge, gray carex, glaucous sedge, or carnation-grass, (syn. Carex glauca), is a species of sedge native to parts of Europe and North Africa. It is frequent in a range of habitats, including grasslands, moorlands, exposed and disturbed soil, and the upper edges of salt marshes. It has naturalized in eastern North America.

Description
Carex flacca leaves are blue-green above, glaucous beneath, to 6 - 12 in in height. The arching leaves are about as long as the inflorescence, 12 - 16 in. The plant spreads in expanding clumps by lateral shoots rooting. Most stems have two male spikes, close together and often looking like one at first glance. Fruits are 2 –, roundish, with a very short beak, under 0.3 mm. They are densely packed on the spike, not loose and gappy like Carex panicea. Female spikes are approximately 2 – long and 4 – wide. Female spikes are typically two, and can be short-stalked and upright, or longer-stalked and nodding.

Cultivation
Carex flacca is cultivated by plant nurseries as an ornamental plant, planted for accent or as a groundcover in gardens and public landscapes. It is also used in drought tolerant landscaping and erosion control plantings. It grows in sun to part shade settings.
