This species naturally grows near water in sun to light shade, but it also grows prolifically in mulched beds containing lots of organic matter. Southern blue flag is a beardless iris that attracts bees, hummingbirds, and the occasional butterfly. The roots and foliage are mildly toxic, so animals tend to not eat this plant.
