About

Galium sterneri or limestone bedstraw is a plant species of bedstraw in the coffee family. It is native to northern Europe in countries that border the North Sea and Ireland but not further south than northern Germany. It tends to be found in grassy or rocky areas and is often associated with limestone. The species was only scientifically described in 1960.

Where it grows

Galium sterneri is native to northern Europe in the countries of Norway, Denmark including the Faroe Islands, Germany, Ireland, and the United Kingdom. In Norway it grows in just a small area in the southwest facing the North Sea. It is widespread in Denmark, but is only reported from a small area of northern Germany in Schleswig-Holstein. In Ireland the species is most often reported in an area in the central western part of the island, but with widely scattered reports from the north. On Great Britain it grows in more rugged areas such as in Wales, the northwest of England, Scotland, and Orkney. In the UK it has been found growing at elevations as high as 975 meters on Creag Mhor.
