Morning glory type flower but what the heck is it?

O.k., I live in NC. I have a flower that seems to have volunteered in my flower bed. Pretty sure I didn't plant it. The flower itself looks exactly like a morning glory and opens and closes and is the same size as morning glory flowers. Each plant has 3 or 4 blooms at a time. This plant, rather than being a vine, has a sturdy purplish stalk and green jagged leaves about four inches long and 1 1/2 wide. Doesn't have a smell. Each plant is about a foot tall. The blooms will stand erect for a few days and then droop downward like trumpet flowers. What the heck is this thing? Thank you in advance.

It isn't bind weed, the flowers on bind weed are tiny. It sounds like it is a wild morning glory.
Reply:Sounds like field bind weed, and if it is you have got a battle on your hands.
