The heat and lack of rain has taken their toll on these beauties. My Black-Eyed Susans don't like where they are living, and seem excessively intolerant of a dry spell. They are close to pine trees, and I'm wondering if they are one flower that doesn't like the pine needles becoming the predominant, free, and natural mulch through the flower bed. I've noticed the last two summers, that my drive to and from work has no purple coneflowers growing along the highway. I need to head either north or south to see them.
