Agrostis scabra is deciduous. The dark-green, simple leaves are alternate. They are linear with entire margins and parallel venation. The foliage is porous.
Flowers and Fruits
Agrostis scabra produces yellow flowers from June to July.
The grasses produce only few brown caryopses in summer.
Agrostis scabra is native to Northeast Asia, North America and Greenland and is naturalized in Germany and Austria.
The grasses prefer a sunny situation on moderately moist soil. The substrate should be comparatively poor with a pH between 6 and 8. The plants need a soil depth of at least 30 centimetres for good growth. They tolerate temperatures down to -35Â°C (USDA zone 4) and need a frost-free period of at least 13 weeks.
Tolerance of special soil conditions
- low: soil salinity, anaerobic soil, drought, calcareous soil
The ornamental value of Agrostis scabra lies especially in the attractive autumn aspect.
