Lolium arundinaceum

Lolium arundinaceum, the tall fescue (also placed in Festuca and Schedonorus), is a robust, tufted perennial grass forming dense clumps 0.5 to 2 m tall, with short rhizomes in some forms. The leaf blades are broad, flat, dark green, stiff, and conspicuously ribbed on the upper surface, with rough margins and prominent claw-like auricles clasping the stem at the base. The inflorescence is an erect, often nodding, branched panicle bearing many large, several-flowered spikelets. The lemmas are awnless or only shortly awned. Native to Europe, North Africa, and temperate Asia and widely introduced elsewhere, tall fescue grows in damp meadows, pastures, roadsides, and disturbed ground, and is extensively sown as a pasture, forage, and turf grass, often harbouring a symbiotic fungal endophyte.
