Japanese Water Iris 'Lapetus': Mythic Waterside Beauty

'Lapetus' grows 24-36 inches tall in its preferred aquatic habitat. The flowers of Iris ensata are characteristically large, flat, and beardless, with six petals (three standards, three falls) creating a circular outline. This cultivar likely displays a color combination worthy of its Titan namesake—perhaps deep, majestic tones or striking patterns.

Cultural needs: consistently wet soil or shallow water (2-6 inches), full sun to part shade, acidic rich soil. Plant rhizomes 2-3 inches deep. These irises are heavy feeders—fertilize in spring. Divide every 3-4 years. 'Lapetus' brings a touch of mythology to the water's edge, a Titan among garden plants.
