Green flowers may be caused by aster yellows

I had purple coneflowers this summer that never turned purple. Many of the flowers were green. What causes this?

coneflower

Coneflowers are one of the many species that may be affected by a disease called aster yellows.

There is a disease called aster yellows that may be affect coneflowers and many other species. Several years ago, I learned from Extension agent Bob Ary that the condition, which is an infection of a phytoplasma spread by leafhoppers, can cause a variety of symptoms: green flowers,  stunting, yellowing, abnormal shoots, tiny leaves that emerge from the seed heads.

In most cases, a plant infected with aster yellows will eventually die, but even if the plant lives, there is the chance that the condition could spread to other plants by any insect that feeds on the plant.

Aster yellows can’t be cured, and it’s not practical to try to control leafhoppers, Ary said. Garden experts say that the disease is sporadic enough that it may only affect a few plants in a bed. When you remove the plant, it’s also a good idea to remove nearby weeds that may be secondary sources of the disease.
