Many of the species are important
pasture plants, used extensively by
grazing livestock.
Kentucky bluegrass (
Poa pratensis) is the most extensively used cool-season grass used in
lawns, sports fields, and
golf courses in the United States.
Annual bluegrass (
Poa annua) can sometimes be considered a weed. According to second-century physician
Galen, the roots of certain species are good for treating fresh wounds and bleeding. In the sixteenth century,
Poa grasses were used to treat
inflammation of the kidney. Some of the
Poa species are popular for gardens and for landscaping in
New Zealand. ==Insect foodplant==
