2-3 ft. | Graceful blue flowers boldly veined with a touch of yellow, rise above the narrow pointed leaves in late spring. Harlequin Blueflag is a natural for sunny boggy areas, its native habitat, but it also thrives in average soil, and even red clay. Its grasslike foliage creates a beautiful silhouette at the edge of a water garden. Established plants grow into large showy clumps. Try Harlequin blueflag in your perennial border or naturalized in a wet area. The genus Iris can support up to 12 lepidoptera species. | Northeastern North America |
