Quack Grass

About 100 species make up this genus of perennial grasses common in northern temperate regions. Though a pernicious weed to gardeners, quack grass (Agropyron repens syn. Elymus repens) is an important medicinal plant that has appeared in herbals and pharmacopoeias since the time of Dioscorides (first century CE). It is a gentle, well-tolerated remedy, included in many preparations for the treatment of prostatitis, with no side-effects. The name Elymus comes from the Greek elymos, "a cereal".

Perennial with numerous rhizomes, to 3mm (1/8in) across, and dull green, linear leaves. Stiff erect flower spikes, with spikelets arranged in zigzag formation, are produced on long stalks in summer.
