Varieties of beardless Irises include the Siberian Iris and the Japanese Iris. These beautiful flowering plants are ideal for landscaping in a border but can also work well almost everywhere in the garden, as well as on the edges of ponds. These plants with their graceful foliage are attractive even after the blooming period is finished. They are available in a range of vivid colors. What makes these irises unique is their lack of a beard, a fuzzy stripe on the top center of each of the three lower petals of the bloom. Their foliage also resembles ornamental grass while the leaves of the bearded irises are thicker and more fan shaped.
