Irises are one of the easiest and reliable perennial garden plants to grow, needing only a sunny location and good drainage. These majestic flowers are very drought tolerant, and actually require less attention than almost any other garden flower. Irises are available in virtually every hue, innumerable intricacies of color combinations, multi-hued, contrasting beards, and other unique color patterns. The reblooming irises are real treasures in your garden with repeat blooms in summer, spring, and fall! Considering their beauty, long bloom period, durability, and range of colors, there's really no reason not to include iris in any sunny garden!
