The leaf sheaths are closed in the lower half or the lower two thirds of the plant. They have a deep longitudinal furrow. The lowest leaf sheaths are often reddish purple.

Occurrence
The distribution area of the amethyst fescue extends from Central and Southeastern Europe to northeastern Turkey. It thrives on moderately dry, base-rich, mild to moderately acidic, humus-rich, often clayey stone or gravel soils in sunny pine steppe forests, in pine bushes, on the edges of forests and in gravel floodplains. In Central Europe it is a character species of the Erico-Pinion association, but also occurs in associations of the Mesobromion or Caricion ferrugineae associations.
use
The amethyst fescue is rarely used as an ornamental plant for heather gardens.
