From Flora of Indiana (1940) by Charles C. Deam

Infrequent to frequent throughout the state. It is most frequent along roadsides and in waste places and has sparingly escaped to open woodland. Introduced as a forage plant. The Indiana farmers whom I have interrogated call it English bluegrass.

FNA 2007, Gould 1980, Kearney and Peebles 1969

Common Name: tall fescue

Duration: Perennial

Nativity: Non-Native

Lifeform: Graminoid

General: Large tufted perennial with stems to 1.5 m, glabrous auricles that are falcate and clasping, sometimes with an undulating flange.

Vegetative: Blades flat 20-40 cm long, 4-18 mm wide, ligule membranous and glaucous, 1 mm.

Inflorescence: Spikelike panicle 8-50 cm long with 2 branches per node, erect to spreading with laterally compressed spikelets 8-13 mm long, 1.5-2.5 mm wide with 3-10 florets; disarticulation above the glumes and between the florets lower glumes 4-7 mm, equally wide, lanceolate to oblong, 3-7 veined, unawned or awned, awns to 18 mm, straight; upper glumes 4.5-7 mm; lemmas 5-9 mm, awns absent or to 4 mm, terminal or attached below the apices.

Ecology: Found in disturbed sites and along stream banks from 3,000-6,500 ft (914-1981 m); flowers April-September.

Distribution: Introduced to every continent and found throughout N. Amer., in every state in the US.

Notes: Distinguished by being a robust perennial bunchgrass with pronounced, ciliate auricles (top section of leaf sheath wrapping around the culm), where they are glabrous in F. pratensis; flat, wide leaves; and a condensed to semi-open panicle of spikelets with multiple florets, possessing rough-hairy lemmas.

Ethnobotany: Unknown

Etymology: Schedonorus is from Greek schedon, for near or nearby and nardos for spikenard, while phoenix is the Greek name for the date palm.

Much like no. 1 [Festuca pratensis Huds.], often taller, to 2 m; old sheaths pale stramineous, only tardily disintegrating; blades coarse and thick, prominently ridge-veined above, 4-10 mm wide, with ciliate auricles; first node of the panicle with 2-3 branches, each with 5-15 spikelets, these mostly 3-6-fld; first glume (3-)4-6 mm, the second (4-)5-9 mm; lemmas 7-8.5+ mm, usually scabrous distally, the awn 0.3-2(-4) mm; 2n most often = 42, sometimes 28, 56, 63, 70. Native of Europe, widely planted in our range and elsewhere in the U.S., and readily escaping. (F. elatior, a rejected name)
