Galium × pomeranicum

Galium × pomeranicum is a species of plants in the family Rubiaceae, named for the region historically called Pomerania, now divided between Germany and Poland. The plant is apparently of hybrid origin, a cross between G. album × G. verum, though established in the wild. It is widespread across most of Europe and sparingly naturalized in a few locations in North America (New York, Massachusetts, Connecticut and New Brunswick).
