plant sale text: Savannah iris is a late blooming iris often found growing in swamps and wetlands in the coastal plan and is perfect for a bog garden. The sepals are widely spreading and then arching downward with prominent dark purple veins and a white to yellow signal.  During the winter period, depending on the severity of the winter, the leaves generally die, to re-grow next spring. When new plants are planted they take a year to settle in before flowering.
