bent grass
bent grass any species of the genus Agrostis of the family Gramineae ( grass family), chiefly slender, delicate plants native to cool climates. Many are used for forage or lawns. Important species naturalized from Europe include the creeping bent ( A. palustris ), a lawn and putting-green grass; colonial bent ( A. tenuis ), frequently used in lawn mixtures; and especially, redtop ( A. alba ), called also fiorin and herd's-grass. Redtop, a perennial with reddish panicles, is much used (often mixed with clover) for pasture and hay in NE America; it is also effective in erosion control. The cloud grass ( A. nebulosa ), native to Spain, is cultivated for use as an everlasting . Bent grass is classified in the division Magnoliophyta , class Liliopsida, order Cyperales, family Gramineae.
