Moist meadow. Galium mollugo or album; don't know how to tell them apart. www.google.com/url?sa=t&rct=j&q=&esrc=s&s... (2003), writing about G. mollugo, says, "Plants with more erect inflorescences and larger flowers are sometimes recognized as a distinct taxon, G. album." Perhaps both sp. are present; I see 2 distinct flower sizes in the foliage shot. Unless that's something else entirely.
