The cultivar 'Sea of Dreams' is a pale lavender blue with darker veining and a yellow center on the falls. The stalks are branched and stand 35 inches high with up to 5 flowers on each stalk. It blooms in early to mid season with a mild fragrance and may rebloom. The thin, grass like foliage remains a highlight throughout the summer. In 2005 Sea of Dreams 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. 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.
