'Vi Luihn' has large, stunning cobalt blue flowers in late spring. It stands 34 inches high and blooms in mid to late season. In 1975 Vi Luihn was awarded Honorable Mention by 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
