Savannah Iris is a perennial bulb native to just 5 states in the southeastern U.S.A. with showy blue-purple flowers. In Nc it is found in shaded, rich, swamps and wetlands in the coastal plain. The fragrant showy purple flowers appear from May to June. and it can form colonies from spreading rhizomes.
This plant is native to boggy soils but will grow in drier conditions. However, if dry for too long it doesn't bloom well.
