Vegetative characteristics

The common fescue reed is a deciduous, perennial, herbaceous plant and reaches heights of 90 to 180 centimeters. It forms subterranean runners . The habitus is reed-like. The stalks are upright.

The leaves are divided into leaf sheath and leaf blade. The leaf sheath is completely open. The ligula are up to 6 inches long. The leaf blade is 6 to 12 inches wide. The upper side of the leaf is clearly rough forward.

Generative characteristics

The paniculate inflorescence is up to 30 centimeters long. The elongated spikelets are rounded on the back, contain two flowers and have no awns. The obtuse glumes are of different lengths, the spikelet is longer than this. The lemmas are spiky one to three times, glabrous, smooth or slightly rough and have 1 to 1.5 millimeter long tufts of hair at the base.

The flowering time is in June and July.

The number of chromosomes is 2n = 28.

ecology

The common fescue reed grows as a geophyte , hemikryptophyte or helophyte . The pollination is carried by the wind.

Occurrence

The distribution area of Scolochloa festucacea extends from northern Europe and eastern central Europe to Mongolia and from subarctic North America to the central United States. The common fescue reed occurs in Germany scattered in Brandenburg and rarely in northeastern Saxony-Anhalt on the lower Havel and in Mecklenburg-Western Pomerania from the east to Peene-Randow. A neophytic occurrence in Bavaria has died out again.

The habitat of Scolochloa festucacea is the reed bed in stagnant or slowly flowing water. Scolochloa festucacea occurs in plant communities of the Glycerietum maximae, the Phalaridetum arundinaceae or in those of the Alnion association.
