Blue blooms are hard-sought and highly prized by home gardeners. Whether your palette is bright and fiery or subtle with soft pastels, a splash of cool tones never goes amiss. And no bloom does blue quite like the elegantly swirling and ruffling bearded iris. The five iris in our Heavenly Shades of Blue Collection are exceptional in many ways. We picked reliable rebloomers, prestigious award winners, fragrant varieties, and of course some of the most divine shades of blue around. You can depend on them to return for years to come, and to put on a remarkable performance each and every time.
