Is something wrong with my coneflower?
I got a clipping of this around May, immediately planted it and it’s done pretty well throughout the summer! It’s in mostly sun, partial shade. I’ve had some gorgeous blossoms from it! Only recently has it started to droop and grow on the floor so I had to stake them up as you can see in the photo. Another worry is the color. It’s like greenish and browned edges. I’m not sure if it’s just end of season and this is normal for it. I live in southern Michigan for zone reference.
