This bluegrass with a wide Eurasian distribution is present in all regions of Italy. It grows in mowed and fertilized lawns, in disturbed vegetation, along the edges of elder thickets, on neutral to sub-acid, silty-clay soils rich in nitrogen compounds, from sea level to about 1200 m (maximum to 1900 m), but the species is rare in the Mediterranean belt. It rarely occurs in the outer belt of the Sardinian temporary ponds, in shaded areas. The genus name is a Greek word that means 'grass'; the species name comes from the Latin 'trivium', with the meaning of 'vulgar', 'trivial', 'common'. Flowering period: May to September.
