This gorgeous iris is unmatched by its elegant presence in the garden. The silhouette of the Blue Diamond Dutch Iris bloom looks somewhat like a bird in flight, gently drifting above the rest of the garden. The 4" flowers emerge in late spring to early summer and stay in bloom for a period of 2 to 3 weeks. To lengthen the bloom time, plant bulbs in 10 to 14 day intervals in the fall.
