Creeping bentgrass

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. It flowers in July and August.
