The cultivar Dreaming Spires has blue to lavender flowers streaked with white in late spring to early summer. It stands 2 feet high with thin grass-like foliage that remains a highlight throughout the season. As a Siberian iris, Dreaming Spires lacks the beard of colored hairs at the base of each fall that other types of irises have. Typically these irises grow together in thick clumps that keep out weeds. The classic Fleur de Lys, which has been a symbol of royalty throughout history, was an adaptation of the iris flower. The name Iris was taken from the Greek goddess of the rainbow to symbolize the many colors of this flower.
