Bearded irises are among the most popular ornamental irises, prized for their large, ruffled flowers in a wide range of colors and their prominent fuzzy beards on the lower petals. These rhizomatous perennials bloom in spring and early summer and are relatively easy to grow in well-drained soil. They are excellent for borders, rock gardens, and cut flowers.
