Deschampsia flexuosa, commonly known as wavy hair-grass, is a species of bunchgrass in the grass family widely distributed in Eurasia, Africa, South America, and North America.

[1] Wavy hair-grass, Deschampsia flexuosa, has wiry leaves and delicate, shaking panicles formed of silvery or purplish-brown flower heads on wavy, hair-like stalks.

Deschampsia flexuosa is found naturally in dry grasslands and on moors and heaths.

It is also an important component of the ground flora of birch and oak woodland.

[2] The plant has a preference for acidic, free-draining soil, and avoids chalk and limestone areas.
