It is a common weed of cultivation, known in the Americas as annual bluegrass.
It occurs as a common constituent of lawns, where it is also often treated as a weed, and grows on waste ground.
Many golf putting greens, including the famously fast Oakmont Country Club greens, are annual bluegrass, although many courses have converted to creeping bentgrass (Agrostis stolonifera).

It has appeared on King George Island in the Antarctic South Shetland Islands  as an invasive species, as well as on Australia's subantarctic Heard and Macquarie Islands.
