Poor photographs, but could this be Woodruff?
No interactions present.
Leaves and habit different. Given the location perhaps Galium palustre.
Definitely a bedstraw I thought, but palustre is not in my (somewhat primitive) field guide.
Time to get a better book! Perhaps Collins or Rose. I would say it was either Galium palustre or possibly G. uliginosum.
