'Cantab' has very small, pale blue flowers with lighter tips and deeper blue falls with a yellow blotch. It blooms in late winter or early spring with a mild fragrance. The flowers stand only 4 to 8 inches high and are perfect in a rock garden or scattered in the lawn. Iris reticulata, often called reticulated iris, is native to Turkey, the Caucasus, Northern Iraq, and Iran. The name reticulata refers to the netted or reticulated pattern on the dry bulbs. The name iris was taken from the Greek goddess of the rainbow to symbolize the many colors of this flower. The classic Fleur de Lys, which has been a symbol of royalty throughout history, was an adaptation of the iris flower.
