A bad weed of cultivated land in Britain and Europe, but apparently only a
minor weed in Australia. This grass is particlularly difficult to eradicate due
to its perennation by rhizomes. As well as the production of hay, Tzvelev
(1983) recorded that this species is used as a diuretic and poultis substance.

Indigenous to Europe
and temperate Asia. Introduced to N and S America, New Zealand and all states
of Australia except Queensland and N.T. Flowers Oct.-Mar.
