The cultivar 'Over the River' has lovely blue standards and falls with a small white signal at the base of each fall. It stands 30 inches high and blooms in mid season, while the thin, grass like foliage remains a highlight throughout the summer. Siberian irises lack the “beard” of colored hairs at the base of each fall that other iris groups have. Typically these irises grow together in thick clumps which keep out weeds. 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.
