Can someone please help me identify a problem with my coneflowers. I dug out the original landscaping plans for my back garden. Originally, white swan and purple coneflowers were planted. Last year, I had pale purple flowers.....this year, the petals are coming but seem light green. I have a few that are purlish...but not too vibrant. Can you tell me if I have a disease or am I just too eager and the petals will come in one of their original colors? I will try to post a picture too.
p.s. I've been lurking and enjoying this forum for many years.
