Japanese Water Iris 'Prairie Glory': Elegant Beauty for Moist Gardens

The Japanese Water Iris 'Prairie Glory' (Iris ensata 'Prairie Glory') brings refined elegance to water gardens, boggy areas, and consistently moist borders. This 1972 introduction by Hazzard represents the graceful beauty that has made Japanese irises prized by gardeners for centuries. Known synonymously as Iris kaempferi, this species offers a distinctly different aesthetic from bearded irises—flattened, orchid-like blooms atop slender stems that sway gently in the breeze.

Growing Notes

Unlike bearded irises that demand sharp drainage, Japanese water irises thrive in consistently moist to wet soils, making them ideal for pond margins, stream banks, and rain gardens. 'Prairie Glory' typically reaches 2-3 feet in bloom, with foliage that remains attractive throughout the growing season. Plant in rich, acidic soil with ample organic matter. These irises benefit from division every 3-4 years in early spring or immediately after flowering. They are heavy feeders—apply a balanced fertilizer in spring and again after bloom for the most spectacular display.
