About Carex sempervirens Vill.
Carex sempervirens Vill. is a vigorous, perennial grass-like plant. It grows 20 to 50 cm tall, is hairless, has a very tenacious rootstock, and produces stems that are leafy only at the base. Its leaves are 2–4 mm wide, rough in texture, and shorter than the plant's stems. This species produces a single solitary, oblong, pale brown male spike. Its female spikes are spaced apart from each other, oblong in shape, somewhat loose in arrangement, and always held erect. Sheathing bracts are often shorter than the flower stalks, and bear brownish, lanceolate scales. The utricles are rusty brown, oblong-lanceolate, measure 5–6 mm long, have faint veins, and taper to a long, split two-pointed beak. It flowers between May and August. Carex sempervirens grows in chalky, nutrient-poor grasslands and rocky mountain habitats, and thrives at altitudes between 1500 and 2400 m.
