'Giant Rose' is a Wonderful Pink Historic Iris and One of My All time favorites. It's Blooms are Huge and Breathtaking! I often forget about it, because it blooms from ML to Very Late Season for us, long after most of my other pink iris have bloomed out. So this is a Great One to plant in with other Earlier Blooming Pink iris beds to Extend the Bloomtime of Your Pink Section. Another one of the Best Rose Color Tall Bearded Iris Ever Created.
