Creeping bentgrass

Description

Agrostis stolonifera is stoloniferous and may form mats or tufts. The prostrate stems of this species grow to 0.4–1.0 metre (1 ft 4 in–3 ft 3 in) long with 2–10-centimetre (0.79–3.94 in) long leaf blades and a panicle reaching up to 40 cm (16 in) in height.

The ligule is pointed and up to 5 millimetres (0.20 in) long. This differs from common bent, Agrostis capillaris, which is short and does not come to a point.

The leaves are tapering, often with a blue-grey colour. The grass is not tufted and the spikelets are red and tightly closed within the panicle.[5] It flowers in July and August. 

ligule is pointed up to 5mm long leaf blade

Distribution

It can be found growing in a variety of habitats including woodlands, grasslands and meadows, wetlands, riparian zones, and as a pioneer species on disturbed sites. It is native to Eurasia and North Africa (Algeria, Morocco and Tunisia). It is possible that it may also be to native to northern parts of North America, and in any case it has been widely introduced and naturalised on that continent and in many other places.

It is a constituent of wet habitats such as marshy grasslands. Some of its species have adapted to contaminated conditions and can cope with heavy metals. It can exist up to 2,500 feet (760 m).
