The bulbous bluegrass is a species with a sub-Mediterranean distribution present in all regions of Italy. It grows in dry meadows, on the edge of roads, on embankments and slopes, on decalcified soils which are poor in humus and dry in summer, from sea level to the montane belt. The species is rare in the outer belt of the Sardinian temporary ponds, in contact with sheep pastures. The genus name is a Greek word that means 'grass'; the plant reproduces vegetatively by bulbils that often appear in the place of flowers, hence the specific name. Flowering period: April to July.

Italian name(s): Fienarola a ligule grandi (Italia), Fienarola bulbosa (Italia), Fienarola bulbosa pseudoconcinna (Italia), Poa bulbosa (Italia), Poa bulbosa pseudoconcinna (Italia).
