I had a hanging basket of them that were feeling a little under the weather given to me by a dear friend. 2 of the 3 are now doing quite well.
I do wish I knew how to save seed of them or something to be able to start my own for next year, but my research has been fruitless. No fruit for Bunilla
edit : the Petunias that I have may or may not make seed- as I am not sure if they are the ones that are infertile? Either way, I will be holding out and watching for some seed pods to form to at least try.
