Plant Profile: Iris tridentata

Savannah Iris is a perennial bulb that thrives in just five states across the southeastern United States, showcasing vibrant blue-purple blooms. In North Carolina, it typically grows in the shaded, nutrient-rich environments of swamps and wetlands found in the coastal plain. The plant produces its fragrant, striking purple flowers from May to June and can create colonies through its spreading rhizomes.

While this species is naturally suited to boggy soils, it can adapt to drier conditions. However, prolonged dryness can hinder its blooming potential. For optimal growth, it is best to provide this plant with moist to wet conditions in sandy soil, ideally in partial sunlight to light shade. Additionally, it can thrive in a container, as long as there is about an inch of soil covering the bulb.
