About Carex flacca Schreb.
Carex flacca Schreb. has blue-green leaf upper surfaces and glaucous lower leaf surfaces. Mature plants reach a height of 15 to 30 cm (6–12 inches). Its arching leaves are roughly the same length as the plant's inflorescence, which grows to 30–41 cm (12–16 inches). This plant spreads into expanding clumps via rooting lateral shoots. Most stems bear two male spikes that grow close together, and they often appear to be a single spike at first glance. Its fruits are 2–2.5 mm (0.08–0.10 in), roundish in shape, and have a very short beak under 0.3 mm (0.012 in) long. The fruits are densely packed along the spike, unlike the loose, spaced arrangement of fruits found on Carex panicea. This species typically produces two female spikes. Female spikes measure approximately 2–4 cm (0.8–1.6 in) long and 4–6 mm (0.16–0.24 in) wide. They can be short-stalked and upright, or longer-stalked and nodding. In cultivation, Carex flacca is grown by plant nurseries as an ornamental plant. It is planted as an accent plant or groundcover in gardens and public landscapes. It is also used in drought-tolerant landscaping and in plantings for erosion control. It grows well in locations ranging from full sun to part shade.
