This one is not specifically Norwegian, of course, but here it reaches uncommon size and spread. This one feels itself excellent in the middle og asphalt and concrete.
Believe it or not, but this is my favorite from what you posted so far.
Common everywhere survivors. I like your find, environment, composition, contrast in colors.
I spent a good part of the afternoon today digging these up from the lawn. I definately dislike them, but actually they don't do any harm. This shot is nice with the green contrasting against the concrete.
