Iris ensata is a spectacular wet growing species, deciduous in winter, with closely branched rhizomes and erect, bright green 2-3 foot leaves. Still taller, branched stems appear in summer, bearing enormous blossoms. 'Flashing Koi' produces flowers which are colored white overall with reddish purple markings surrounding the bright gold flash at their centers. Sun, most soils, constant moisture. They can actually be immersed in water; however, better clumps and more flowers may result from growing them in moist, rich soil. Hardy to 0 degrees F. or below.
