I'd love to see a full size pic that you used to make the banner petunias, if you can find it. I looked at the petunias plant database and I saw a pic you submitted, but not one that had a lot of pink flowers (like in the banner) in it.
@Marilyn, I had to go back to 2012 to find the original picture I used for the banner. Here it is with a few other pics of the volunteer petunias from over the years. Such a lovely gift of nature that I don't have to buy or plant, just enjoy!
