Move or Mauve?

This really pretty flower is growing all over the hardcore in our front garden.

My son's started a project of building a Driveway in approx 2007, still not finished & there are lots of broken bricks etc at the side of the path as well as in the hole dug for the Driveway.

Now as you can see, there are pretty weeds / flowers growing all over them.

I don't mind because they are hiding the mess.
Not sure what they are called though.

Move the mess, or Mauve over mess!

I like Mauve over mess :o)
