|Last year my pink coneflowers were beautiful. This year some were again beautiful, but others in the same flowerbed never turned pink.They started out looking like normal buds, but stayed green with abnormal bud growth. Do you have an answer as to why this happened? Thank You Joan Pursel|
|You?re almost certainly looking at the effects of a disease called aster yellows. Aster yellows affects many types of plants in many ways, but when it strikes coneflowers (Echinacea), the flowers turn an unusual green color ? even the flower petals are green. Many times, the flowers will be distorted in numerous ways, and the flower parts might even appear leafy. It?s usually passed along from plant to plant by leafhopper insects. The best way to prevent the spread of aster yellows is to watch for (and eliminate) plants that become infected.
