Flowering in summer to fall, it is infrequent throughout Indiana on low grounds in woods, along ditches, and on the borders of lakes and ponds. It was more common before the extensive destruction of wetlands. Formerly used as a medicine, a practice that was discouraged due to the adverse symptoms caused by overdoses. It makes an impressive addition to any moist, semi-shaded garden site. This plant contains lobeline, which caused poisoning when misused as a home medicine.
