Echinacea/Purple Coneflower, green center?
I don't have a picture handy, but I will try to post one when I get home. I have a number of purple coneflowers that didn't bloom, they put out this odd green growth where the center should be. Somewhere in the deep recesses of my brain I thought I read this is caused by a virus. Does anyone know what is wrong? Should I pull them?
