Species of grass

Agrostis stolonifera (creeping bentgrass, creeping bent, fiorin, spreading bent or carpet bentgrass) is a perennial grass species in the family Poaceae. It is widely used as turf for golf courses.

Agrostis stolonifera is stoloniferous and may form mats or tufts. The prostrate stems of this species grow to long with long leaf blades and a panicle reaching up to in height. The ligule is pointed and up to 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.

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 the most commonly used species of Agrostis. It is used for turf in gardens and landscapes, particularly on golf courses. In 2017, the USDA agreed not to regulate it at Scotts request, which meant that Scotts "will no longer be legally required to pay to clean up the grass after 2017, though it has promised to do so." A 2004 gene flow study (with scientific sampling methods) documents gene flow on a landscape level, with a maximum at and (respectively) in sentinel and resident plants observed by scientist, located in primarily nonagronomic places such as irrigation ditches. Other work in transgenic bentgrass looks into salinity tolerance. The improved performance of the transgenic plants was associated with higher relative water content, higher sodium uptake and lower solute leakage in leaf tissues, with higher concentrations of Na+, K+, Cl and total phosphorus in root tissues, and with higher auxin accumulation rate in the root tissue. This transgenic plant can survive in the presence of 1.7% sodium chloride (half seawater salinity concentration), while the non transgenic line and wild type plants cannot.
