The False Indigo Bush is found throughout Maryland but may be absent from the Allegheny Plateau. Most common on the coastal plain but becomes increasingly rare to the west. Because of its use in horticulture, favored planting in hedge rows and use in windbreaks many populations may not be "wild". Wild False Indigo Bush seems to favor river and marsh edges and wet thickets with lots of sunlight.
The long purple flowering spikes are diagnostic.
Host plant for Four-lined Cabera Moth.
