Carex sempervirens, called the evergreen sedge, is a species of tussock-forming flowering plant in the family Cyperaceae, native to the mountains of Europe.

[3] Carex sempervirens is a vigorous, perennial grass-like plant, growing between 20–50 cm in height; glabrous, with a very tenacious rootstock; the stem leafy only at the base.

Sheathing bracts are often shorter than the peduncles; with brownish, lanceolate scales.

Utricles are rusty brown, oblong-lanceolate (5–6 mm), slightly veined, ending in a long, bifid beak.

[5][6] Carex sempervirens favours chalky, nutrient-limited grasslands[7] and rocky mountain habitats.
