wildflower being weird

This wildflower plant is really weird. It grows wild on the side of the house on a little sliver of ground. It only blooms in the morning and not even every day.

Don't know what it is but is very delicate and pretty when it does bloom.

I keep meaning to print out the pictures of wildflowers and take to the local nursery to see if they can identify the flowering plant. Of course I could look them up on the Internet but I just never seem to have time.
