kudzu, the aster has the smaller darker green leaves.
Later I noticed some bamboo bark lying on the ground. I collected these three pieces to bring home with me. As I was getting in the car Gary said he had been bitten on his legs by no-see-ums. They itched him for over a week. I was spared as they were near the water and I didn't go over there. When we got home, I had Gary rub baking soda water on his legs which helped with the itching, and he used some lavender spritzer which also helped. Gary counted 92 bites on his legs; only Gary would count them. Ha.
