Do you know if it grows in Indiana? I ask because there’s a telephone pole at a four way stop near me that has a plant that looks like a Morning Glory and it has grown to the top of the pole. It’s huge. Could that possibly be bindweed?
It’s possible. See if you can get a close look at it. The link I posted has pretty good pics for comparison.
As far as I know, bindweed grows clear south to Texas. Possibly further.
