Hi Keith,
Those are some big zinnia blooms. Hopefully you are going to save seeds from the very largest ones. You might even make cross pollinations between your largest specimens, if you wish to seem some variations in them and possibly some even larger blooms.
I don't have any huge blooms right now -- I do have several a bit larger than 5 inches across, but none that are really large.
In past years I have had a few blooms a bit more than 7 inches across, and I hope to repeat that and eventually get zinnias 8 inches across. But that may take a few more seasons of experimentation.
Thanks for posting your pictures. You are doing a good job of growing nice zinnias. If you have any more pictures of your zinnias, we would love to see them.
