Deschampsia flexuosa (L.) Trin.
Deschampsia flexuosa, commonly known as Wavy Hair Grass, is a grass.
Deschampsia flexuosa was already described and the name validly published by Carl Linnaeus. It was Carl Bernhard von Trinius, however, who reclassified it into todays valid botanical systematics in 1836.
The grasses are comparatively short-lived and reach heights of 15 to 60 centimetres.
Deschampsia flexuosa is evergreen. The dark-green, simple leaves are alternate. They are linear with entire margins and parallel venation.

- none: drought
- low: calcareous soil
The recommended planting distance is 30 centimetres, the grasses are best planted in groups of 5 to 10.
