Deriving its name from the Greek goddess of rainbows, this classic perennial is a showy staple for any late spring or early summer planting. Today's irises are available in an array of colors and patterns, including bold, solid tones, and multi-colored, extravagantly patterned displays. Because of the color options, gardeners can get creative with their displays, planting one variety en masse, choosing multiple varieties or incorporating iris into perennial flower beds. Requiring hours of direct sunlight to bloom, iris excel when planted prominently along garden borders, or within cut flower arrangements. Exhibiting deer resistance and drought tolerance, this low maintenance perennial is a pleasure to grow.
