Rocky Mountain Iris (Iris missouriensis) brings cool, alpine charm to any garden spot that mimics its native, moist mountain meadows. With elegant pale blue/purple blooms atop clumps of arching leaves, it offers early‑season drama without demanding extra care. After flowering, it settles into low maintenance, allowing soils to dry. 

This iris thrives along swales, near seasonal creek beds, or in lower yard areas that retain a bit more moisture. It’s also well suited for open woodland understories, pollinator borders, or mixed native grass plantings where it can spread via rhizomes, forming graceful colonies over time. Bees, butterflies, and even hummingbirds are drawn to its blooms, while its deer-resistant foliage makes it a smart pick for peaceful, wildlife‑friendly landscapes. Add one now, and enjoy its quiet, seasonal beauty for years to come.
