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:
