False Indigo is a tall native shrub of floodplains and stream banks across North America with compound leaves and spike-like clusters of tiny purple flowers with orange stamens, creating an unusual two-tone effect. It is a nitrogen-fixer and is the larval host plant for silver-spotted skipper and other specialist insects. Dense stands provide cover for many wildlife species.
