Aster Yellows Disease in Coneflower (Echinacea)

Coneflowers are one of my favorite perennials. Environmentally there are few things to worry about with them. They are drought tolerant, bloom prolifically, and help to create a beautiful landscape. Unfortunately there is one major issue that can destroy whole gardens of these perennials: Aster Yellows. Recently I filmed a short video on a coneflower in my garden that has Aster Yellows disease. It’s easy to spot. Check out the video below for more information on Aster Yellows disease:
