Recognizing the plant

Identification depends on small details of the leaves and flower clusters. The Swiss flora’s key describes dark-green leaves, a dense panicle and blue-green spikelets tinted violet. Leaf sheaths on new shoots are joined for a quarter to half their length, and a leaf cross-section shows five vascular bundles. The plant is associated with siliceous rather than lime-rich substrates. Info Flora: Festuca ovina aggregate identification key

Native range

Kew places its native range from the Pyrenees to the Alps, including Spain, France, Switzerland, Italy and Austria. Catalonia’s habitat manual records its alpine grasslands from roughly 1,900–2,000 metres upward, principally on acidic soils.

Ecological relationships

In these Pyrenean grasslands, documented neighbours include alpine gentian, spiked woodrush and Agrostis rupestris. At higher sites or where snow remains longer, Carex curvula becomes more prominent as this fescue declines. Generalitat de Catalunya: Manual dels hàbitats de Catalunya, habitat 36i1
