[Poa pratensis L.]
bluegrass is the second most widely grown cool-season species in North Carolina
because it has a dark green color, a medium to fine texture, and, due to its
aggressive rhizome system, can recover from stresses. It prefers fertile,
well-limed soils and full sun to moderate shade. Kentucky bluegrass is often
mixed with other cool-season grasses like tall fescue to enhance the ability of
the turfgrass stand to recover from stresses. Kentucky bluegrass is often
confused with tall fescue and/or perennial ryegrass. However, Kentucky
bluegrass has a boat-shaped leaf tip and distinctive light-colored lines on
both sides of the midrib.
