Rubia peregrina, the common wild madder,[1] is a herbaceous perennial plant species belonging to the bedstraw and coffee family Rubiaceae.

Etymology
The genus name Rubia derives from the Latin 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 possibly comes from the Latin peragrare meaning "to move or travel" or "to proceed" and refers to the ability of this plant to easily expand itself in its habitat.
Description
The stem is woody, hairless, square and climbing and reaches on average 50–250 centimetres (20–98 in) 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 5 mm (0.20 in) in diameter.[2]
Distribution
It is mainly present in the Mediterranean Europe (Spain, Portugal, France, Italy, Greece and former Yugoslavia), in Great Britain and in North Africa.[2]
Habitat
This 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 0–1,000 metres (0–3,281 ft) above sea level.[2]
