Bent Grass, a large genus of stiff grasses with small flowers. Some varieties are important lawn and pasture grasses. Creeping bent, often used on lawns and golf courses, has very slender leaves and creeping stems. If small patches of this grass are planted, they will soon grow and cover a large area. Brown bent grows to nearly 18 inches (45 cm) high. It is also commonly used in lawns. Redtop, a species of bent grass planted for hay as well as for lawns, grows about three feet (90 cm) high.

Bent grasses make up the genus Agrostis of the family Gramineae. Creeping bent is Agrostis stolonifera; brown bent is A. canina; redtop is A. gigantea.
