Southern blue flag iris (Iris virginica) is a native iris with large, elegant, pale blue to deep purple flowers. This wetland wildflower with sword-like leaves grows 2-4 feet tall in full sun. Southern blue flag iris grows in marshes, swamps, and along ponds in northern Florida. It is an ideal plant for rain gardens, water gardens, retention ponds, and drainage ditches. However, it can tolerate normal garden soils with regular watering. Deer resistance is high. Though visited by butterflies seeking nectar, it is pollinated by bumblebees and long-horned bees. The dark purple lines near the flower center are nectar guides, visual cues that help pollinators find nectar and pollen faster. The Southern blue flag iris is blooming now near the pond at Sopchoppy Depot Park.
