Flowers look like greater stitchwort, but the leaves don't look the same as the photo in my Wild flower book.
It looks like common whitlow grass to me.
One of the wintergreens?
i have it in my garden and i have always know it as woodruff.. well that is what my Granddad callled it..
dunno if it is the proper name.. it spread very easily each year it comes up and i find it will tolerate any conditions.
sorry should spell woodrough..
The leaves look wrong for it to be woodruff...
Definitely not woodruff. If the OP lives near the sea, I would suggest Scurvy Grass. Not a grass at all, common on road banks.
Just found this link - weed flower images. Take your pick because it looks very similar to 3 known weeds.
I am trying to see the lower leaves better The flower looks like what: We call milkmaid but in the flower books they call it stitchwort. shall look again when I find the magnifying glass.
