My coneflowers were doing great, with all the rain we have had.All 6 of them now have leaves curling and twisting and yellowig. Planted in sun. What is it and what should i do.

Hi @Janece Welcome to NGA.

Are the plants in fast draining soil? The same rain that started them growing may now be drowning their roots.

I would work the soil back from the roots of a plant and see if they are overly wet. If so, Then perhaps you could move them to containers or a raised bed.

Here is a link on Echinacea diseases...none of the symptoms really matched your description.

Echinacea need very good drainage , if not you will get crown rot and that will do them in.

Janece. Is there any chance you could post a picture of the plants? Do they look anything like the picture on the top left on this page link below? I think it's unlikely that all six would simultaneously get aster yellows but just to rule it out. Maybe also consider whether any kind of pesticide has been sprayed in the area:
