Galium parisiense is a species of flowering plant in the family Rubiaceae known by the common name wall bedstraw.

It is an annual herb producing lightly hairy, very thin, much-branched, erect stems 15–25 centimetres (6–10 in) tall.

[2][3] Wall bedstraw is native to the Mediterranean Basin of southern Europe and northern Africa, plus Turkey, Iran, and the islands of the eastern North Atlantic (Great Britain, Madeira, the Azores, the Canary Islands, Cape Verde).

The species is also naturalized in some parts of North America, mostly on the Pacific coast of the United States and Canada but also at scattered locales in the southeastern US from Texas to Maryland.

[3] When introduced, it may appear in urban environments such as among cobble stones in Ghent and in railway marshalling yards in Antwerp.
