Agrostis exarata Trin.
Agrostis exarata is a grass.
Agrostis exarata was described by Carl Bernhard von Trinius in 1824. The name is considered as validly published.
The grasses have a erect habit and reach heights of 1,5 to 1 metres. They spread slowly, the main growing season is from spring to fall.
Agrostis exarata 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 exarata produces yellow flowers from May to June.
The grasses produce only few brown caryopses in summer.
The plants produce rhizomes which give rise to vegetative spread.
The grasses prefer a sunny situation on moderately moist soil. They prefer soil with a pH between 5,5 and 7,5 and need a soil depth of at least 25 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, drought, calcareous soil
- medium: anaerobic soil
