EtymologyThe genus name Rubia derives from the Latin {{lang|la|ruber}} meaning "red", as the roots of some species (mainly Rubia tinctorum) have been used since ancient times as a vegetable red dye. The specific epithet is the Latin adjective {{lang|la|peregrinus, -a, -um}} meaning "foreign, alien, exotic, strange." DescriptionThe stem is woody, hairless, square and climbing and reaches on average {{convert|50|-|250|cm}} long.[2] The evergreen leaves are sessile, glossy, leathery, oval-lanceolate and toothed on the margins. They are arranged in whorls, usually with five or more leaves radiating from a single node. The small flowers have five petals and are pale green-yellowish, about 5–7 mm in diameter,[2] arranged at the top of long stalks. The flowering period extends from April through June.[2] The hermaphroditic flowers are pollinated by insects (entomogamy). The fruits are fleshy green berries, black when ripe, about {{convert|5|mm|abbr=on}} in diameter.[2] DistributionIt is mainly present in the Mediterranean Europe (Spain, Portugal, France, Italy, Greece and former Yugoslavia), in Great Britain and in North Africa.[2] HabitatThis stress resistant weed is typical of Mediterranean scrub. It grows in thickets, bushes, hedges, stony grounds and along the roads and paths. It prefers dry soils, at an altitude of {{convert|0|-|1000|m}} above sea level.[2] GallerySynonyms
