''Agrostis capillaris'', the common bent, colonial bent, or browntop, is a
rhizomatous and
stoloniferous perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also ...

'' comes from the
Greek word meaning
forage plant, ''agros'' meaning "a field".
It is found growing in neutral to acidic soils. It has a very fine texture and like most bent grasses grows very dense. Although this species is used on golf courses, providing some of the best ball playing surfaces in the world, it also produces a spectacular visual appearance when maintained properly. It provides an excellent home lawn but is not tolerant of heavy use. Colonial bent is fairly easy to grow from seeds and fertilization of the lawn is not as intense. This grass also takes longer to establish than creeping bent. However, it does not require the intense maintenance.
Many internet sources describe it as being the tallest of the bent species. However, C. E. Hubbard describes its height as ranging from 10 to 70 cm high, whereas the black bent ''
Agrostis gigantea'' is 40 to 120 cm. Marjorie Blamey, Richard and Alastair Fitter also describe black bent as being taller.
Description
It forms a dense sward of fine leaves. The
ligule is short and does not come to a point. This differs from creeping bent, ''
Agrostis stolonifera'' in which it is pointed and up to 5mm long.
The flowering
panicles appear from May until June. They are finely branched and look like a purple haze from a distance. The panicle persists in winter after the seeds have been shed.
Environmental conservation
''Agrostis capillaris'' forms a constituent of
purple moor grass and rush pastures, a type of Biodiversity Action Plan habitat in the UK. This habitat occurs on poorly drained neutral and acidic soils of the lowlands and upland fringe, and can be found in the south-west of England, especially in
Devon
Devon ( ; historically also known as Devonshire , ) is a ceremonial county in South West England. It is bordered by the Bristol Channel to the north, Somerset and Dorset to the east, the English Channel to the south, and Cornwall to the west ...
. It is found on
upland pastures throughout the UK.
