Agrostis capillaris, commonly known as common bent, is a grass.
Agrostis capillaris was described by Carl Linnaeus in 1753. The name is considered as validly published.
The comparatively fast-growing and short-lived grasses have a erect habit and reach heights of 20 to 70 centimetres. They spread rapidly, the main growing season is in spring and summer.
Agrostis capillaris 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 capillaris produces panicles of light-green flowers from June to July.
The grasses produce an abundance of brown caryopses in summer.
The plants produce rhizomes which give rise to vegetative spread.
Agrostis capillaris is native to the whole of Europe, Turkey, the Caucasus, northern Iran, West-Siberia, East Siberia, Afghanistan, Pakistan, India, Tunesia and the Canary Islands and is naturalized in North America, Central America, South America, Greenland, South Africa, Lesotho and Swaziland, Australia and New Zealand.
The grasses prefer a sunny situation on moderately moist soil. The substrate should be sandy, gritty-sandy, loamy, sandy-loamy, clay, sandy clay or loamy clay and comparatively rich with a pH between 4,9 and 7,5. 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 17 weeks.
