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. http://www.provenwinners.com/plants/index.cfm?doSearch=1&searchKeywords=superbells&page=3 which you will copy and paste the link, or go to provenwinners.com and find the plant search icon. 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.
