Are my cone flowers infected? #700998

Asked July 15, 2020, 10:20 AM EDT

I have a sneaking suspicion that my cone flowers have developed Aster Yellows or have mites. Could you please look and let me know what you think? Thank you!

Most of the flowers look normal.  Aster yellows would cause the center to send up tall or even conelike material  You could remove the plants that you are concerned about and keep the others and just watch them.
