This plant grows like a weed along all the borders of my garden. It has been identified for me at least once, but I can’t remember what it is. If you know, you’ll score points for filling me in on it. The flower is about 2 or 2 1/2 inches wide. Several people below guessed it was a petunia and I was sure they were wrong, but turns out I’m wrong. Its popular name is “Mexican Petunia,” even though they are not closely related.
