This is Rudbeckia laciniata, sometimes called Cut-leaved coneflower. The green leaves of this plant are good to eat in the spring. Also called sochan. This plant grows in areas that get wet periodically. Now it's dry here, in the Wabash River bottomland, although there is plenty of ground water. This is in West Lafayette near the Purdue Crew team facility. Very common all up and down the Wabash. Like many plants in the sunflower plant family, it flowers in late summer.
