Bentgrasses (Agrostis spp.)

Bentgrasses are fine-bladed perennial grasses. Commonly used as a turfgrass, bentgrasses are mostly found in cool climates and in areas of frequent irrigation. Bentgrasses can invade into adjacent turf and irrigated landscaped areas by the growth of its creeping, horizontal stem (stolon).
The collar has a membranous ligule, but no auricles.
The mature plant develops dense sod patches. Leaves are narrow, normally much finer than other turf, except fine fescue, which has rolled, rather than flat leaves. Creeping aboveground stems root easily at stem joints (nodes). Leaf blades and sheaths are hairless.
Bentgrasses reproduce by seed and aboveground creeping stems.
