They are bell shaped flowers, annual not perennial, not on a vine, with a white center and purple around the edges beside purple stamens. Somehow for the life of me I cannot find a pic of them online or any information on what mode of flowers they are.
Answers:    its a Petunia. Not all own the white in the middle though. But some do.
Could they be a type of ******* explicitly the first thing that comes to mind
