Superbells Pink Gem

Proven Winners (I saw a plant tag in one of your other photos) makes a Superbells® Coral, Calibrachoa hybrid (pink/orangey shade). These look like mini petunias. Also, Superbells® Pink, Calibrachoa hybrid (pink/less red). Also, Superbells® Trailing Rose, Calibrachoa hybrid (hotter pink)
There are many colors. Cameras do not make true colors sometimes, so I listed several close matches for you to look at and pick.

Good luck! Pretty picture.

looks more like calibrachoa, it is in the same family as petunia (Solanaceae)

I would leave the ? mark there for awhile. I think it may be something else. But it is a beautiful pictue.
