'Tiffany Lass' has dark blue violet standards and falls with lighter blue style arms.  The base of the falls blends into brown.  It stands 28 inches high, blooming in early to mid season.  It may re-bloom.  In 1992 it received Honorable Mention from the American Iris Society. 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, while the thin, grass like foliage remains a highlight throughout the summer. 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.
