Type of coneflower that has an odd blooming problem.

Asked September 22, 2019, 10:30 AM EDT

So I got this plant from a nursery last fall so this is its first full year in the garden. The tag seemed to get lost over the winter so not sure what it is.The plants flowers seem to die without blooming I'll get that spike head for the flower but alot of them just seem to die before actually blooming. Those black and brown flower heads never had any petals. Just kinda curious what's going on if I need to do anything special for this plant. It's the only plant in my garden with this problem. It gets full sun after noon.

I believe your plant has symptoms of aster yellows. This is carried by leaf hoppers. The plant needs to b removed before it spreads. Here is information: https://extension.umn.edu/plant-diseases/aster-yellows
