Qualities

Rough bluegrass is best adapted to wet, cool, and shady areas. A cool-season grass, it is sometimes used for shaded turf in the fog belt areas and can be used to overseed dormant bermudagrass.

Identifying tips

A fine-bladed yellow-green grass. Leaves are folded in the bud, there are no auricles, and a membranous ligule is present. Leaf blades slightly taper to form a boat-shaped tip. The lower surface of the blade is glossy; the upper surface has a characteristic median midrib. Rough bluegrass has a shallow root system and spreads by stolons.

Maintenance

Moderate maintenance. Rough bluegrass requires rich soils and a lot of water. It tolerates low temperatures, but will not tolerate wear, heat, or drought.
